  • Fossil Club at Seven Stars Quarry (Club Members Only)

    • 26 Apr 2025
    • 8:30 AM - 3:00 PM
    • Seven Stars Quarry
    • 0

    Search for trilobites and more on this exclusive NHSM Fossil Club field trip. The mostly shale rock from the Middle Devonian Mahantango Formation is home to a diverse set of prehistoric life including brachiopods, bryozoans, mollusks, corals, graptolites, and even cephalopods, squid-like animals with shells.

    Trilobites, the site’s main draw, originate from one of the earliest groups of arthropods, the phylum which includes insects, spiders, and centipedes on land and crabs, lobsters, and barnacles in water. They were one of the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species found. Trilobites finally disappeared in the Permian-Triassic extinction about 251.9 million years ago.

    Surface collecting, digging, and chiseling are methods used for the hunt here. Absolutely no power tools allowed! You will be asked to leave!

    Due to the limited number of spots available, we are limiting the number of guests each registrant can bring. Thanks for understanding.

    Contact the club coordinator (mfalk@marylandnature.org) with any questions.

    Springtime warmth means more birds overhead, on the move to their summer homes. Join ecologist John Canoles for a birding hike at Swan Harbor Farm, a popular bird spot with diverse habitats, including wetlands, forest, waterfront, and a dredge spoil area.

    Swan Harbor Farm has a total species list of over 277 types of birds, with over 190 species reported in a typical April. Migrant and resident birds that can be found there include common sightings of bald eagles, osprey, and red-tailed and red-shouldered hawks. Common mergansers, canvasback, and lesser scaup can be seen plying the waters along the shoreline. Solitary sandpipers, lesser yellowlegs, and spotted sandpipers can be found in the fields and wetlands. A beaver pond hosts prothonotary warblers, common yellow-throat, black-throated green warblers, and scarlet tanagers. Baltimore and orchard orioles can be seen in the forests and hedgerows. Swan Harbor is listed as the #1 eBird hotspot in Harford County.

    We will hike through the various habitats, taking our time and enjoying the view of the bay. The total mileage will be less than two miles. The trails may be muddy depending on the weather and are fairly flat but can be uneven in places.

    During the field trip, we will be participating in the City Nature Challenge, logging all of our observed species using the iNaturalist platform. The Challenge is a collaborative effort involving cities all over the world to identify as many wildlife species as possible in their urban setting over a 4-day period. Last year, Baltimore made more than 10,000 observations of more than 1,600 species, and we are hoping to break that record this year.

    John Canoles is an ecologist focusing on the identification and assessment of natural resources and the creation of natural upland and wetland habitats. He is also involved in nature education, having helped design the nature walk and Butterfly House at Ladew Gardens and the Accessible Trail at Cromwell Valley Park, and has taught “Introduction of Birdwatching” classes for Johns Hopkins Odyssey Program, Community College of Baltimore County, and Cromwell Valley Park. John also writes a monthly Nature Notes column for the Baltimore County Country Chronicle newspaper. He is a member of the Harford Bird Club and the Harford County Land Trust and is on the board of Trustees for Ladew Topiary Gardens.

  • Wild Edibles: Morel Hunt with Nick Spero

    If truffles are out of your price range, morels are the next best thing. Prized for taste and versatility by chefs worldwide, morels emerge for only a short time in spring. Knowing where to look for morels is one important factor in the hunt. Lucky for us, Nick Spero knows all the clues. He knows the rich forests where morels grow and how they are intertwined in a symbiotic relationship with certain trees. We’ll learn how indicator plants can tell us when the morel growing season will start and end. And how the right combination of warmth and rain brings morels popping their heads out of the soil.

    We will discuss collection methods and how to prepare our findings for optimal taste and nutrition. To limit our impact on the park, let’s concentrate on learning to identify and sample taste rather than foraging, which may damage an area when too much is taken.

    Please note that morels are very temperature and moisture dependent. We will do our best to find them, but like all natural things, we make no guarantees.

    Our field trip leader, Nick Spero, spends his retirement outdoors as an avid hunter and fisherman. Primitive technology has piqued his interest since childhood. Here is a video produced by NPR about Nick.

    Join waitlist

    Our newest Maryland Big Tree tour takes us to Baltimore County to experience the record holders at Hampton National Historic Park. Fourteen trees on this historic site are registered in the Big Tree Program database with eight holding Baltimore County Champion titles and one with a state championship as well.  The county champs include both native and non-native species, including American holly, tuliptree, white ash, cedar of Lebanon, (allegedly brought here in a shoe box), European beech and linden trees, London planetree, and the big winner, a saucer magnolia with both county and state awards. All of these trees are specimens, planted specifically for the enjoyment of the mansion owners, and can easily be seen along a loop trail about 1.5 miles long.

    This field trip will be showcased in a locally produced film, Growing into Greatness: Maryland’s Champion Trees, produced by Robert Lemieux, associate professor in the Communication Department at McDaniel College. The film discusses programs such as Maryland Big Tree that are designed to preserve our natural surroundings and promote an appreciation for nature. By showing how easily these trees are accessed, the project hopes to promote greater involvement between its viewers and nature. Filming will be done as unobtrusive observers, following the group as it tours with a handheld camera. Those agreeing to be filmed will need to sign a provided standard waiver. If you choose to not be included in the filming, that choice will be respected.

    Our field trip leaders are Marc Lipnick and Linda Barker. Marc retired in 2014 after 29 years as a Quality Assurance Engineer with the Maryland State Highway Administration. He is a Master Naturalist, and volunteers with the Big Tree Program, Baltimore County Forestry Board, and the Old-Growth Forest Network. He spends his days hiking, finding and measuring big trees, and identifying and cataloging wildflowers in Maryland’s parks. Linda Barker owned a landscape company for 25 years and retired in 2015. With a physical sciences and horticulture background and as a lifelong gardener and outdoorsperson, she joined the Big Tree Program as a volunteer to measure trees and joined their board in 2017. She also volunteers for the Baltimore County Forestry Board.

    The Big Tree Program originated in Maryland in 1925 by the State’s first Forester, Fred Besley. The national program began in 1940, modeled after the Maryland program. It rewards owners who care for their big trees since about 90% of registered trees are backyard trees, as opposed to forest-grown trees. Trees grown in backyards tend to have less competition and receive more nutrients and water from the owners. Each big tree owner receives a certificate, a thank you letter, and a list of trees of that species registered in Maryland. Additional benefits of the program include providing a database to those studying trees who may need to know where big examples are located. The database serves as an important record over time for changes to species distribution and is also handy for those looking for locations of rare and unusual species. The Big Tree database base is accessible online at https://www.mdbigtrees.org/.

    While registering for this field trip, you will be asked to consider a donation to the Big Tree Program at the state level. Your donation will assist them in cataloging new trees as found and recorded.

  • Asteroids Impacting the Earth

    • 01 May 2025
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    The most famous asteroid has to be the Chicxulub Event. Remember? 65 million years ago an asteroid roughly 6 to 9 miles in diameter hit Earth in what is now Mexico, killing 70% of all species on Earth, including the dinosaurs. Although immense impactors like the one that devastated the entire planet 65 million years ago are rare, Near Earth Objects (NEO) of many different sizes can pose serious threats.

    In this talk, Dr. Sethanne Howard will define asteroids, explain where they live in our Solar System, and describe what happens when they impact the Earth. She will also discuss the pieces of asteroid extracted in situ and returned to Earth by a science mission. What do they tell us? And can science fiction be made real? Can we avoid a big asteroid hit?
    Sethanne Howard is the first woman to receive a degree in physics from the University of California, Davis. She received a Master’s Degree in nuclear physics from Rensselaer Polytechnic Institute and a PhD in astrophysics from Georgia State University. Between her bachelor’s degree and PhD she worked for many years in various scientific fields and taught high school physics and university astronomy. She also worked for a US Naval facility as an oceanographer and meteorologist. She worked with x-ray satellites at Los Alamos National Laboratory where she received two awards for education outreach. At NASA Headquarters she managed several operating NASA astrophysics satellites and mission programs and created the initial web pages for NASA’s Office of Space Science. Before coming to the US Naval Observatory (USNO) in October 2000, she spent three years at the National Science Foundation as the Program Manager for Extragalactic Astronomy and Cosmology and also Executive Secretary for the international Gemini Telescopes Project.
    She is now retired. Her hobby is the history of women in science and technology, and she maintains a web site dedicated to this effort: http://4kyws.ua.edu.The web pages are now an integrated part of many school and textbook curricula. Her book on the history of women in science was just published: The Hidden Giants.

  • Insect Study Merit Badge Class

    • 03 May 2025
    • 9:00 AM - 2:00 PM
    • 6908 Belair Rd, Natural History Society of MD
    • 6
    Register

    Insect Study merit badge provides Scouts with a glance into the strange and fascinating world of insects and their relatives. At any given time there are approximately 10 quintillion (that is 1 with 18 zeros) insects living on the planet. Scouts will learn about some of these tiny creatures with strange and amazing abilities, see insects that undergo startling changes in habits and form as they grow, and learn how insects see, hear, taste, smell, and feel the world around them. If you are prepared, and have read the pamphlet, this class will help you fulfill most of the requirements for this badge.

    Pre Work: Requirements 5, 6 (create a scrapbook of insects you have personally observed in the wild), and 9 (rear an insect) cannot be entirely completed on the day of this course. If possible, try to complete these requirements prior to the class. For requirement 9, rearing mealworms or super worms from the pet store is probably the easiest option (https://www.wikihow.com/Raise-Mealworms). Take a few pictures along the way to show completion.

    The course is being taught by a professional entomologist who is also a Merit Badge Counselor and Scout Master.

    Requirements:

    • Registered Scout with a Troop
    • Permission of a Parent or Guardian
    • (Preferred) Approval from Scoutmaster or Assistant Scoutmaster on BSA Blue Card

    Things to remember to bring for this Merit Badge Class:

    1. Prework
    2. Merit Badge Blue Card properly filled out and preferably signed by your Scoutmaster
    3. Insect Study Merit Badge Pamphlet (available from the Scout shop or online)
    4.  Class A Scout Uniform
    5. Weather appropriate clothing for the time of year and location of the class for outdoor participation
    6. Supporting documentation or project work pertinent to this merit badge which may also include a Merit Badge Workbook for reference with notes (http://usscouts.org/mb/worksheets/Insect-study.pdf)
    7. A positive Scouting focus and attitude
    8. Packed lunch that will be eaten outside (weather dependent)

    Most merit badges are not designed to be completed in a single session with an instructor, so it is not always possible to walk away with a completed and signed blue card at the end of a program.

    Almost every badge requires some independent work by your scout. We call this “pre-work” because, if these requirements are performed prior to our program, we can complete and sign the merit badge card. Otherwise, those requirements that were completed will be signed off on the blue card and the partial card can be completed by any qualified counselor at a later date.

    ABOUT THE INSTRUCTOR: Dr. James (Jim) Young is the curator of primitive Lepidoptera at the National Museum of Natural History as well as the curator of arthropods for the Natural History Society of Maryland. I primarily work on the identification of immature stages of Lepidoptera encountered in international commerce. Jim is a certified merit badge counselor and has been active in Scouting for many years at many levels.

    Payment and Cancellation Policy: Payment is due online at the time of registration. Cancellations made seven or more days in advance of the event will receive a refund minus a 5% processing fee. Cancellations made within seven days of the event will not receive a refund. Events and field trips with fees of $10 or less are not refundable at any time unless canceled by NHSM. NHSM retains the right to update or change these requirements at any time.

     

    The Natural History Society of Maryland is a volunteer-led non-profit organization, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible.

    Thank you for your support!

    Aristotle said that nature could only be understood through observation, analysis, and classification. Humans have devised many ways to observe, analyze, and classify the natural world. Join our friends from the Johns Hopkins Center for Functional Anatomy and Evolution to learn about their favorite tools in evolutionary biology, comparative anatomy, and phylogenetics.

    This interactive workshop will start with Dr. Donald Morgan and PhD candidate Savannah Cobb discussing how comparative anatomy helps us understand living and fossil animals. In the afternoon, Dr. EJ Huang will introduce phylogenetics and explain how scientists determine evolutionary relationships.

    Get hands-on with real skeletal specimens and datasets to learn how researchers infer the ecology of extinct species and map them onto the tree of life!

    • Taxonomy is the science/study of classification.
    • Phylogeny is the science/study of evolutionary relationships between organisms.
    • Comparative anatomy is the study of how different species’ anatomical structures compare and contrast with one another.
    It’s a critical moment for this work. There are potentially 8 million species on Earth, and researchers have only described about 1.5 million. Some believe we are experiencing the 6th great extinction event meaning that many will go extinct before we can name them. It’s a race to record life as it disappears.

    Don’t be intimidated by science. All are welcomed – wherever you are in your understanding and study of nature.
    NOTE: Please bring a lap top to the class.

    Join waitlist

    Join us for an evening sail on the Lady Maryland. Here is your chance to learn a bit about sailing as well as engage in hands-on marine science from our friends at the Living Classroom Foundation. Activities will include water quality testing, plankton trawling with microscope exploration, trawl fishing for marine life, oyster dissection, bird morphology and identification, setting sail, and steering the ship. Bring a light dinner and beverage: alcohol is allowed, too.
    The Lady Maryland is a replica of a pungy schooner, originally built in Maryland and Virginia between 1840 and 1880. Pungies were a significant development in vessel design, uniquely adapted for carrying perishable cargo on the Chesapeake Bay. Pungies have a hull shape similar to the famous Baltimore Clippers making them extremely fast, an important asset when delivering cargo. The Lady Maryland was built in 1986 to provide a hands-on opportunity to sail a historic vessel and learn about the ecology, history, and economics of the Bay.
    Our time will be spent touring the Inner Harbor and Fort McHenry. In addition to the science, the crew is very knowledgeable about Baltimore sights and local history, and they love to share stories with guests.
    • Everyone must sign a liability waiver for Living Classroom. It will be emailed to all participants.
    • Ages 18 and up
    • Temperatures drop when out on the water, especially in the evening.
    • Bring drinks and a light dinner. An ice chest will be available.
    • Closed-toe shoes are mandatory on board.
    • Illegal drugs, marijuana, or firearms are not allowed.
    • Allow plenty of time to park in the garage, walk to the dock, and check in. The ship leaves promptly at 6 pm.
    • A restroom is available onboard.

    Experience archaeological excavation alongside the experienced team at the Blue Rock Heritage Center. This Washington Boro location was home to the Susquehannock people’s largest village, and was inhabited in the time of John Smith’s travels in 1608. Numerous graves and burial sites have been discovered here, as well as a butchery and cooking area. Archaeologists estimate the village size to have been 250,000 square feet with the ability to house 1,700 people.

    Our day will start with a brief tour to view artifacts and learn local history with Charlie Douts, president of the center. Included in the collection are three petroglyphs that were removed for preservation purposes from Walnut Island in the Susquehanna River. The most mysterious petroglyph shows a carved symbol, unlike other designs in the area, with a pattern similar to the crosshatches found in our modern tic-tac-toe game. After our tour, we will discuss the methodology of archaeology, the timeline of the area, and what to look for when excavating and artifact sequencing with Debbie Saylor, curator of Blue Rock.

    We’ll break for a short lunch, then join Paul Nevin, the principal investigator of the site and president of Chapter 28 of the Society for Pennsylvania Archaeology. We will learn how to sift, proper troweling techniques, recording, and how to recognize soil changes by color and features. All artifacts found will be properly recorded and stored at Blue Rock for further research at their archaeology lab in the lower level of the center. Blue Rock Heritage works with the Native American non-profit group, Circle Legacy, which is involved in all displays and excavations.

    Take a hike on the seafloor of an ancient ocean at Soldier’s Delight Natural Area. Known as “The Great Maryland Barrens” to early pioneers, this area encompasses 1,900 acres and is the largest remaining serpentine ecosystem in the eastern United States. It is home to 39 rare, threatened, or endangered plant species, insects, rocks, and minerals.
    These barrens are characterized by having shallow soil composed of serpentinite, an oceanic rock created when igneous rocks like peridotite from deep within the Earth’s mantle are metamorphosed under sea pressure. This soil type is susceptible to erosion and contains very high levels of magnesium and very low levels of essential nutrients. The flora and fauna of serpentine barrens have adapted to these harsh growing conditions. Colorful asters, prairie grasses, dragonflies, and butterflies may be seen in the oak savannas and grasslands of Soldiers Delight, depending on the season. The remaining barrens cover less than 5% of their original area and are threatened by invading pines and brambles.
    We’ll hike about 1.5 miles to learn about these special plants and insects in this area, as well as how these areas are managed and why they are disappearing. If the group wishes to hike further, that may be possible. The trail and surrounding areas are rocky in places.

  • Hummingbirds - A Boundary Pushing Natural History

    • 15 May 2025
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Hummingbirds have evolved to push the boundaries of vertebrate physiological performance. Although these adaptations have proven to be beneficial to hummingbirds in a wide variety of ways, adaptations are also associated with trade-offs that influence how the birds function and interact with their environment. This talk will focus on hummingbird natural history along with the unique anatomy, physiology, and behavior that distinguish hummingbirds from other vertebrate and avian taxa.
    Jennie Rinehimer, PhD, is an Associate Professor of Biology at Washington College in Chestertown, Maryland. Jennie earned her BS in Biology from Juniata College and a PhD in Biology from Indiana State University where she worked with Steve Lima on avian antipredator behavior in foraging birds. Now in her 11th year at Washington College, her research focus has expanded to also include studies on breeding birds, including how parental age and experience affects reproductive success. Her study species have included mourning doves, wintering mixed-species sparrow flocks, field sparrows, white-collared manakins, and ruby-throated hummingbirds.

  • Stratford Cliffs Spring Fossil Hunt, Fossil Club Members Only

    • 17 May 2025
    • 8:30 AM - 3:00 PM
    • Stratford Cliffs / Stratford Hall Plantation
    • 0
    Join waitlist

    Fossil Club members are invited once again to participate in this ever-popular NHSM event!

    Among the most important fossil research sites in the Mid-Atlantic region, Stratford Cliffs were formed when land replaced an ancient sea. Fossils found here are from the Miocene Epoch, approximately 17 to 10 million years ago, and indicate an ancient sea filled with primitive shark-toothed porpoises, salt-water crocodiles, sea cows, gopher turtles, rays, whales, and sharks. Thousands of shark teeth have been found at the site, including Carcharodon megalodon, or Giant White Shark, with teeth measuring 7 inches or more!

    Located in Montross, VA (on the south side of the Potomac River, adjacent to Westmoreland State Park), these cliffs are part of the Calvert Formation. Most of the land along the shoreline is privately owned, and public access is severely limited, so we are lucky to have this opportunity! Our site is part of the Stratford Hall plantation owned by four generations of the Lee family (and now cared for by the Robert E. Lee Memorial Foundation). The estate encompasses 1900 acres of farmlands and forests on a high bluff overlooking the Potomac River.

    Travel time: The site is an estimated 3-hour drive from Baltimore. Guests are responsible for their own transportation; NHSM cannot provide rides. The exact address will be provided to you via email with your registration confirmation.

    Difficulty: This field trip is moderately strenuous, involving hiking, cold water, and uncertain weather. Depending on what storms may have impacted the river, there could be washed-up trees and debris on the beach, as well as broken glass. There could be a few scramble spots. However, if you do not want to climb over obstacles, you can remain on the beach that is accessible to you. This is a rain-or-shine event.

    Age Restriction: Stratford has a minimum age requirement of 8 years old.

    Cancellation Policy: Cancellations made more than one week before the date of the event will result in a refund, minus a 5% processing fee. No refunds can be issued within a week of the event, but the registration can be transferred to a friend.

    If NHSM cancels this event, all registration fees will be refunded in full.

    If you have questions or concerns about this or other Fossil Club events, please contact the club coordinator (mfalk@marylandnature.org).

    Unique ecosystems lie untouched in the hills and valleys of the Allegheny Mountains of western Maryland. Spend the weekend exploring these pockets of rare plants, birds, and insects with naturalist Jim Brighton, co-founder of the Maryland Biodiversity Project, a conservation and education community specializing in birds and plants of the Mid-Atlantic region.
    We’ll explore seven areas in Allegheny and Garrett counties throughout the weekend. We’ll learn about a remnant boreal fen found in the Finzel Swamp Preserve, a rare sloping gravel wetland at Frostburg Reservoir, and the Piclic Shale Barren, part of the Appalachian Shale Barrens, a rare ecosystem only found in this area of the Ridge and Valley Province of the Appalachians. We’ll hike at Lostland Run Natural Area to see wet cliffs above the upper reaches of the Potomac River, and at Rocky Gap State Park, we’ll walk to a cliff face and the dam spillway. A stop along the C&O Canal is included to search for rare plants and insects. We will finish on Sunday at Sideling Creek to view more shale barrens and dramatic cliff faces full of interesting plants and animals. Potential sightings could include painted trillium, zebra swallowtail, marsh calla, and chalk-fronted corporal.
    A complete itinerary and driving directions will be available the week before the trip. We will caravan between sites. Hiking distances vary, with the possible longest distance of no more than two miles.
    Hotel reservations can be made at the group rate of $149 per night at the Hampton Inn Frostburg. The link will be supplied after registration. You are welcome to stay at any location of your choice.

    Our trip leader, Jim Brighton, is co-founder of the Maryland Biodiversity Project (MBP). Since it began in 2012, MBP has cataloged more than 21,000 species found in Maryland and features the work of more than 28,000 naturalists and photographers.

  • Spawn of the Horseshoe Crabs

    • 22 May 2025
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    What do thousands of horseshoe crabs do when the evening tide is high and the spring moon is new or full? A spawning so huge that people travel to view it from around the world.

    The scene begins with male horseshoe crabs waiting along the water’s edge. As a female moves with the tide onto the beach, the male grabs her shell with his claws, hitching a ride on her shell. Over multiple trips over multiple nights, one female can lay up to 88,000 eggs per year.

    To learn more about horseshoe crab behavior and their important role in the Bay ecosystem, tune in to this talk by Dr. Brad Stevens. The Zoom link will be in your confirmation email after you register.

    Brad Stevens, Professor Emeritus and Distinguished Research Scientist at the University of Maryland Eastern Shore (UMES), worked in Kodiak, Alaska, for over 20 years before coming to UMES, where he used scuba and underwater video to study fish, crabs, conch, and corals. He tells his graduate students, “Always study something you can eat.” Would that apply to the horseshoe crab?

    To see horseshoe crabs in person, join us for our late evening adventure to view the mating crabs at Slaughter Beach on May 26. We’ll meet our horseshoe crab expert, Brad Stevens there to learn about their behavior close-up. Register here: https://marylandnature.wildapricot.org/event-6134514.

    Let’s combine an afternoon of birding for migratory shorebirds with a late-night beach walk at high tide, where we’ll experience a horseshoe crab spawning so huge that people travel from around the world to view it.

    The scene begins with male horseshoe crabs waiting along the water’s edge. As a female moves with the tide onto the beach, the male grabs her shell with his claws, hitching a ride on her shell.  As she builds nests or leaves egg clusters along the beach, the male is pulled with her, fertilizing the eggs. Once the mating is complete, both head back to the water. Most of the action happens late into the evening, after 10 pm. Over multiple trips over multiple nights, one female can lay up to 88,000 eggs per year.

    What is the fate of the majority of those eggs? They become a nutrient-dense meal for thousands of rufa red knots, a robin-sized shorebird that migrates from South America to the Arctic and back each year. Rufas time their stopover in Delaware Bay to coincide with the peak of spawning, feeding almost exclusively on horseshoe crab eggs as they build strength for the next leg of their migration.

    Our beach adventure begins on May 26 with an afternoon low tide to view the red knots and other shorebirds at three stops: the DuPont Nature Center, Marvel Salt Marsh, and Slaughter Beach. We’ll take a dinner break in the town of Milford, then head back to Slaughter Beach for the evening high tide and a shoreline full of horseshoe crabs. This beach is known for having some of the highest counts of horseshoe crabs in the area, with over 60,000 in May 2022 and over 5,000 on the new and full moons in June 2022.

    We will also meet on Zoom on May 22 from 7 to 8 pm. to learn about the horseshoe crab behavior and their important role in the bay ecosystem. Both the Zoom presentation and the horseshoe crab portion of the field trip will be led by Brad Stevens, Professor Emeritus, and Distinguished Research Scientist at the University of Maryland Eastern Shore (UMES). Dr. Stevens worked in Kodiak, Alaska, for over 20 years before coming to UMES, where he used scuba and underwater video to study fish, crabs, conch, and corals. The Zoom link will be in your confirmation email after registering.

    Rob and Carol Blye of the Sussex Bird Club will lead the birding portion of our trip. Rob is a retired biologist with a degree in wildlife biology from Cornell University. He and Carol are avid recreational birders who organize field trips for the bird club.

    Slaughter Beach is about a 2-hour drive from Baltimore. There is adequate parking and restrooms. Plan to stay up very late to see the most action.  Hotels are plentiful in Milford if you choose to spend the night.
    Difficulty: Moderate with the possibility of cold conditions, definitely wet, and darkness

    People always have been interested in snakes, turtles, lizards, and alligators, as well as frogs and salamanders. Amphibians and reptiles—collectively known as herpetofauna—are increasingly important today as their populations are key indicators of the effects of climate change and habitat fragmentation on wildlife. Presented by certified merit badge counselor, Tom Scollins, herpetology curator and leader of NHSM Herp Club, this class will help you fulfill the following Merit Badge requirements*: 1,2,3,4,5,6,7,10. There will be plenty of live and preserved animals on hand.

    Terms and Conditions: Pre-registration and prepayment are required to attend. Spaces are limited.  Cancellations up to a week in advance of the course will incur a $5 processing fee. No refunds made 7 days before the start of the course.

    Things to remember to bring for this Merit Badge Class:

    1. Merit Badge Blue Card properly filled out and signed off by your Scoutmaster
    2. Reptile and Amphibian Merit Badge Pamphlet and Workbook
    3. Scout Uniform
    4. Supporting documentation or project work pertinent to this merit badge which may also include a Merit Badge Workbook for reference with notes
    5. A positive Scouting focus and attitude

    The badge also requires either three months of recorded observation of a reptile or Amphibian in a nature center, zoo or similar location, OR one month care and recorded observations
    of a reptile or amphibian you keep at home. If you have a pet reptile or amphibian already, then the one month of care is a simple option for you. PLEASE do NOT go out and purchase a pet
    reptile or amphibian just to complete the badge! Pet ownership is always a long-term commitment for the life of your pet and should only be undertaken after careful consideration. You may
    make observations at any a nature center, zoo, pet store, or other similar center near your home. NOTE: The Mid-Atlantic Turtle and Tortoise Society is partnering with NHSM on this badge, and will make available foster turtles for purposes of fulfilling the merit badge requirements. You may convert the fostering into adoption. 

    Families can foster an adult box turtle in a Rubbermaid tote or a juvenile aquatic turtle such as a slider, in a 10- or 20-gallon aquarium.
    Anyone who wishes to foster, please  email matts_adoptions@hotmail.com as soon as possible to receive recommended reading and an application, to know what to expect or to find out which type of turtle they’d prefer, and to  set up enclosures to go with the turtles.  A refundable $50 deposit is required when fosters pick up the turtle and supplies. The deposit will be returned when the turtle and supplies are returned.

    * Most Merit Badges are not designed to be completed in a single session with an instructor, so it is not always possible to walk away with a completed and signed blue card at the end a program. Every badge requires some independent work by your scout. We call this “pre-work” because, if these requirements are performed prior to our program, we can complete and sign the merit badge card. Otherwise we will sign partial cards at the completion of our program and will have qualified counselors review assignments on an individual basis at a later date. Note you will have to contact and schedule an appointment with Tom Scollins. NOTE: The Herp club meets monthly at NHSM on the Second Wednesday of every month at 7PM. 

    The Natural History Society of Maryland is a volunteer-led non-profit organization, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible.

    Payment and Cancellation Policy: Payment is due online at the time of registration. Cancellations made seven or more days in advance of the event will receive a refund minus a 5% processing fee. Cancellations made within seven days of the event will not receive a refund.

  • Io Moth Embroidery Workshop

    • 31 May 2025
    • 9:00 AM - 12:00 PM
    • 6908 Belair Rd, Natural History Society of MD
    • 9
    Register

    Students will learn the slow, meditative art of hand embroidery while creating a beautiful image of the Io moth (Automeris io), a species native to Maryland.

    The provided pattern is designed to introduce students to several stitches that produce different lines and textures, such as basic stitch, backstitch, satin stitch, French knots, and more. The pattern also leaves space for a little creative freedom. Students will learn how to finish the hoop so it can be displayed without a frame. Moth size is 4 inches.

    The Io, a Saturniid moth, is named after the Greek tale of Io, the mortal lover of Zeus that a jealous Hera turned into a cow. The male io has a striking pair of brilliant yellow wings, while the female is darker in color. This moth species also has noticeable eyespots on the hindwings that can scare off predators.

    Techniques: Surface design embroidery on fabric in a hoop using several beginner-level stitches.

    Kit: Students will be provided with fabric stamped with the moth pattern, embroidery hoop, needle, embroidery floss in 8 colors, snippers, and instructions to take home. Supply Fee is included in the registration ($22).

    Teacher Bio: Heather Kerley is a mixed media and fiber artist living in Bowie, Maryland with her husband, two cats, and a small backyard wildlife sanctuary. Her art encompasses a diverse range of mediums, from watercolor and collage to embroidery and quilting. However, her interest in sustainability, ecology, and protecting the natural world has remained a consistent theme in her work. As a fiber artist committed to sustainability, she uses found and upcycled materials in much of her work, inspiring creative improvisation and play. Kerley has been teaching art in different venues for over ten years and has been with the Smithsonian Associates Studio Arts Program for over 4 years. She enjoys evolving her classes alongside her own creative journey and cherishes her interactions with students.

  • Osprey in the Wild

    • 05 Jun 2025
    • 11:00 AM - 2:00 PM
    • 0
    Registration is closed

    Look to the sky along the Chesapeake Bay shoreline and you’ll likely see an osprey. The Bay supports the largest osprey breeding population in the world. In the 1970s, osprey numbered 1,500 breeding pairs due to DDT contamination. Now populations have rebounded to an estimated 8,000 to 10,000 breeding pairs in the mid-Atlantic. How do we know stats on osprey population, health, and migration? Ask Park Naturalist Greg Kearns and he’ll answer with his banding tools in hand.

    Join Greg to experience ospreys up close as chicks are banded, measured, and counted at their nesting platforms at Patuxent River Park. Participants may be able to help with banding if the chicks meet the minimum size requirement. The banding data collected is sent to the Bird Banding Laboratory at the Eastern Ecological Science Center to help scientists understand migration patterns, population dynamics, sources of mortality, and bird lifespans. Much of the critical information known comes from tracking and reporting banding data.

    We’ll learn how Greg and his interns have installed and maintained over 100 osprey nest platforms along 25 miles of river and banded over 5,000 adult and juvenile ospreys over the last 30 years. With the osprey population growing, the birds have exceeded the availability of natural nesting sites. Human-made nesting structures are almost always occupied, and ospreys then choose to nest on cell towers and lighting structures. This can create conflicts with human values and needs.

    Please note that all bird observation and handling techniques match or exceed the practices outlined in the Bird Banders Code of Ethics. Our leader, Greg Kearns, is a Senior Park Naturalist with over 40 years of experience and extensive research on the osprey, sora rail, and wetland ecology at Jug Bay. He is an accomplished speaker, photographer, and birder. Greg was named Conservationist of the Year by the Maryland Dept. of Natural Resources in 2006 for his work on the restoration of the wild rice marshes on the river. He also received the Jug Bay Award for significant contributions to the environment and was given the 2017 National Wetlands Restoration and Conservation award from the Environmental Law Institute in Washington, DC. Greg does the technical monitoring work and also makes it accessible to the public through these unique educational opportunities.

    Difficulty: Easy, must have the ability to walk on a dock, climb steps into the boat, and step down to disembark.

  • Hybrid Zone of the Baltimore and Bullock's Orioles - Evolution in Action

    • 05 Jun 2025
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Hybridization occurs when two different species interbreed and produce offspring. While we often think of hybridization in animals as something that’s rare, or something that is a reproductive dead end, it is actually fairly common, especially in birds, and it is an important tool to help us understand how and why species evolved in the first place. In the bird world, it’s estimated that hybridization occurs in at least 10% of all species.

    Hybrid zones, geographic regions where two species overlap and interbreed, have been particular important in shaping our understanding of evolution. In the Great Plains of North America, multiple pairs of bird species hybridize, including the Eastern and Spotted Towhees, Indigo and Lazuli Buntings, and the Baltimore and Bullock’s Orioles.

    The orioles in particular have a long and fascinating history of research dating back to the 1950s, and through this long history of research, we have been able to understand how patterns of hybridization have changed over time. Using an integrative approach that combines morphology, genomics, and climate change research, we have explored the oriole hybrid zone to understand how and why these species hybridize, and what it can tell us about biodiversity and the evolution of species.

    Shawn Billerman works at the Cornell Lab of Ornithology, where he is a science editor with Birds of the World, an online resource and the world’s largest, most comprehensive, scholarly resource for birds that is filled with more than 11,000 species accounts and 250 family accounts. With Birds of the World, he works with authors and contributors from around the world so they can share their passion about the species that they study and update species accounts. He also works with the Clements Checklist team to help maintain taxonomy, where he has a special interest in bird families.

    In addition to his work with Birds of the World, he is also broadly interested in understanding patterns of avian speciation. His past research for his PhD and postdoctoral fellowship, which focused on hybridization between the Red-naped and Red-breasted Sapsuckers as well as birds of the Great Plains, including the Baltimore and Bullock’s Orioles, has taken advantage of museum collections and focused on using hybrid zones to understand how intrinsic and extrinsic processes have influenced how and where species hybridize, and ultimately what factors are important to understanding reproductive isolation.

    “Birds are important because they keep systems in balance: they pollinate plants, disperse seeds, scavenge carcasses and recycle nutrients back into the earth. But they also feed our spirits, marking for us the passage of the seasons, moving us to create art and poetry, inspiring us to flight and reminding us that we are not only on, but of, this earth.” —Melanie Driscoll, Director of bird conservation for the Gulf of Mexico and the Mississippi Flyway

    • Cockeysville, Martin-Marietta Texas Quarry
    • 0
    Join waitlist

    Digging holes seems like child’s play. But not when you’re the crew at Martin Marietta’s Texas Quarry. Their hole isn’t measured in feet, but rather miles: a mile long and a half mile wide, to be exact. This massive pit was the source of marble that built the walkway to the Capitol in Annapolis and the portico for St. Paul’s Cathedral in NYC. Our Washington Monument in Baltimore and a section of the Washington Monument in D.C. are also made from Texas marble. The history of this quarry goes back even further to 1802 and the first Irish immigrants to the region. On this tour, let’s watch the heavy equipment dig and haul while discovering the stories of those immigrants.

    We will learn the history of the quarry, including past and current ownership, and information on daily operations. This tour is based on a scenic overlook above the quarry. From there, we can view the equipment at work in the distance. There is no public access to the quarry pit or the operations since it is a working job site.

    Please note

    • Our meeting location can be found in your registration confirmation email when payment is complete.
    • Watch for additional details in a welcome email a few days before the date.
    • When you arrive, all must sign a Hold Harmless Agreement with Martin Marietta to be on the property.
    • Everyone aged 5 years and older is welcome to attend.
    • Proper outdoor etiquette is required. No climbing, running, or loud voices. Be respectful of our speakers by demonstrating good listening skills.
    • Families are welcome to leave the tour at any time if needed.
    • Photos are welcome.

  • Fossil Hunt at Stratford Hall, Open to All

    • 14 Jun 2025
    • 9:00 AM - 3:30 PM
    • Stratford Hall 483 Great House Road, Montross, VA
    • 33
    Register

    How big is your shark tooth collection? If your answer is between zero and a thousand, join us to search for fossil treasures at Stratford Hall. With private beach access and help from expert volunteers, this trip is a unique opportunity for those looking to learn about ancient life in this area and perfect their fossil-collecting techniques.

    Stratford Hall’s cliffs are part of a series of rock layers formed when ancient seas covered the area. Today, the Chesapeake Bay and rivers like the Potomac erode these old sea floor deposits, giving us a window into the past. These cliffs date from about 8 to 16 million years ago, during the Miocene Epoch. This location is one of the most scientifically important exposures of its kind in the Mid-Atlantic region and the world.

    Fossils that could be found include shark teeth from several different species, including Hemipristis or snaggletooth shark, tiger and tiger-like sharks, sand tiger sharks, C. Hastalis or the ancient white shark, and requiem sharks and shells such as Chesapecten scallop and the Maryland state fossil, Ecphora, a predatory snail. Bones from whales and dolphin-like marine mammals, turtle shell pieces, sting ray dental plates and barbs, crocodile teeth, and fossilized crabs are also possibilities.

    This site is part of the Stratford Hall plantation owned by four generations of the Lee family and is now managed by the Robert E. Lee Memorial Foundation. The estate encompasses 1900 acres of farmlands and forests on a high bluff overlooking the Potomac River. Field trip participants have access to tour the estate while at the fossil hunt.

    Travel time: The site is an estimated three-hour drive from Baltimore in Montross, VA (on the south side of the Potomac River, adjacent to Westmoreland State Park). Guests are responsible for their own transportation. Many choose to spend the night before or after to break up the drive. Hotels can be found in the towns of King George and Colonial Beach.

    Difficulty: This field trip is moderately strenuous, involving hiking, cold water, and uncertain weather. There will be washed-up trees and debris on the beach that will result in scramble spots. If you do not want to climb over obstacles, you can remain on the beach that is accessible to you. However, please note that you will be wading in the water, and in colder months, we recommend wearing waders. Bare feet are never allowed. This is a rain-or-shine event.

    Age Restriction: The minimum age requirement is eight years old. This age limit is set by Stratford, and there are no exceptions. Please respect this policy when registering your family.

    Payment and Cancellation Policy: Payment is due online at the time of registration. Cancellations made seven or more days in advance of the event will receive a refund minus a 5% processing fee. Cancellations made within seven days of the event will not receive a refund. Events and field trips with fees of $10 or less are not refundable at any time unless canceled by NHSM.

  • Quail Forever in Maryland

    • 26 Jun 2025
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Here in the Mid-Atlantic, QF is advocating for and restoring populations of Northern Bobwhite (Colinus viriginanus) through habitat restoration and outreach. Populations of Northern Bobwhite in the Mid-Atlantic have declined by over 6% annually since the 1980’s, with similar declines seen in populations of songbirds and other organisms associated with early successional habitats. In this talk, Sierra and Jack, the local Delaware and Maryland QF biologists, respectively, will cover the history and status of quail in the region, their habitat needs, and the work that QF is doing to connect with local landowners and put more habitat on the ground.

    Pheasants Forever, Inc. & Quail Forever is the nation’s leading upland wildlife habitat conservation organization and employs hundreds of private lands biologist across the country. The goal of Quail Forever (QF), the quail division of Pheasants Forever, is to generate momentum for quail conservation through advocacy efforts to landowners and natural resource agencies, including work on the federal Farm Bill and implementation of quail-specific habitat projects, while striving to provide increased opportunities for hunters and educating the next generation of land stewards.

    Jackson (Jack) Hutchison grew up on the Eastern Shore of Maryland and caught a passion for land stewardship from his father, who is a partner in a family farming operation. Jack received his B.S. in Biological Sciences from Cornell University, where he researched songbirds, while more recently he worked with endangered species in Mississippi with the USFWS. Outside of work, Jack helps on the farm and enjoys hiking, photography, hunting, and birding with friends.

    Sierra grew up near Annapolis, Maryland where she developed a passion for wildlife from a young age through enjoying the natural resources in and around the Chesapeake Bay. She pursued this passion and completed her Bachelor of Science in Wildlife Biology at West Texas A&M University where she involved herself in as many field work opportunities as possible taking her all throughout the state. During this time, she gained the hands-on experience to understand the importance of maintaining habitat for the conservation and management of wildlife. After graduating and just before joining Quail Forever, Sierra worked with the Maryland Conservation Corps to assist areas throughout the state with various projects involving trail building and maintenance, insecticide application, prescribed burning, and invasives removal. Now in Delaware as the state’s Quail Forever Biologist, Sierra continues to enjoy hiking, birding, camping, and has recently picked up learning how to upland hunt.

    Take a step back into history with this unique paddling experience! Located on the Susquehanna River just south of the Safe Harbor Dam is one of the largest concentrations of petroglyphs in the Northeast U.S. Found primarily on two islands named Big Indian Rock and Little Indian Rock, these petroglyphs are thought to be as many as 1,000 years old. The Algonquian people created these rock carvings that can still be enjoyed today, accessible only by kayaks, canoes, or small motorized boats.

    This float is on the Susquehanna River, which is vulnerable to windy conditions, so previous paddling experience is recommended. Our canoes seat 2 adults, so individuals will be paired up with another paddler. If you are not comfortable paddling with a stranger, sign up with a buddy! Please wear comfortable clothing and footwear that you don’t mind getting wet or dirty. There are portable toilets, picnic tables, and a playground at the park, so feel free to bring lunch if you want to hang around before or after your paddle!

    Sail the weekend away aboard a traditional oyster boat of Maryland, the Skipjack Sigsbee. We’ll cruise from the Inner Harbor to our campground at Sandy Point State Park with a full complement of hands-on activities, including setting the sail and steering the boat; trawling for plankton, fish, and crabs; water testing; oyster dissection; and bird morphology and identification along the way. Try your hand at Native American fishing with your handmade fish weir and practice those fancy knots that every sailor should know, too.

    When we reach dry land, we’ll explore the beach, wade, swim, and fish with a seine net before heading off to make camp. We’ll end the day with a warm meal, a rousing game of kickball or frisbee, and a fire complete with all the s’more fixings. Come morning, we’ll pack up camp and head back to the boat to make our way up the bay for home. Be prepared to swab the deck, no joke! All food is included, cooking is done by the staff, and most camping supplies, including tents, are provided. Participants will be responsible for their personal camping gear, such as a sleeping bag and pad. Participants will be expected to help with some camp set-up and dinner cleanup.

    This introduction to the biology, ecology and diversity of lichens will begin in the classroom with an introduction to lichens and a discussion of some of the ways and places that lichens grow. Then we will go on a short walk to find some of the common lichens of Maryland and  demonstrate how to collect, label, and store specimens. The class will conclude back in the classroom viewing the features of the lichens we’ve collected under the microscopes and using keys to identify them. NOTE: Participants will also have the option to bring their own specimens to identify.

    Natalie Howe has been studying lichens with high or low intensity for the past 16 years, and currently lives in Washington DC.  She is a Biological Scientist at the U.S.D.A., and an adjunct teacher of Mushrooms, Molds, and Society class at George Mason University. In the pre-Covid times, she was volunteering with the lichen team at Patuxent Research Refuge in MD, Rock Creek Park in DC and at Liberty State Park in NJ to document the lichens there. For her dissertation research at Rutgers University in New Jersey, she studied the ecology of lichens in the NJ Pinelands.

    Paddle where the Ospreys hatch and the Eaglets learn to fly! Containing one third of Maryland’s tidal wetlands, Blackwater Wildlife Refuge was established as a migratory bird refuge and is now home to over 250 bird species. We will dip our paddles in the shallow waters that muskrats and beavers call home, navigating through the lush, marshy grasses.

    A trip to Blackwater Wildlife Refuge would not be complete without mention of the courageous American abolitionist, Harriet Tubman. Our paddle will take us just a short distance from the Harriet Tubman Underground Railroad National Historic Park, where we’ll highlight her remarkable story of growing up in Dorchester County and courageously guiding 70 enslaved African Americans to freedom.

    Our canoes seat 2 adults, so individuals will be paired up with another paddle. If you are not comfortable paddling with a stranger, sign up with a buddy! This paddle will take place in protected waters. Any level of paddling experience is welcome.

    Once upon a time, three islands floated in the Chesapeake Bay to the east of Baltimore. While looking like tiny scraps of land to most people, others saw potential. Thirty years and 90 million cubic yards of material later, Hart-Miller Island was born. The Army Corps of Engineers and Maryland Department of Natural Resources rebuilt the 1,100-acre island to safely dispose of dredging material while adding habitat for bay birds and wildlife. Join us for a morning boat and bus tour of the island, offered through Maryland Environmental Service. As an important habitat for migrating shorebirds, nesting terns, and grassland-nesting songbirds, the site was developed with upland grassland and wetlands that flow into an extensive pool. A one-acre nesting island was constructed after a Maryland Ornithological Society survey was completed. We will be on the lookout for birds while on the bus and at all stops.

    Bring a picnic lunch to eat near the beach on our last stop on the bus tour, Hart-Miller Island State Park. Snow cones and cold drinks may be available for purchase at their small store, however, it may be closed for the year due to budget cuts. If it is open, the store only accepts cash, no credit cards.

    Please note that while this tour is offered for free from MES, we appreciate your donation to cover our costs in offering this program.

    Difficulty: Easy to moderate, participants need to be able to board a boat with assistance, climb stairs, and hike .5 miles on a gravel road.

  • Seaweeds and Human Nutrition: Unlocking Marine Potential for Health and Agricultural Innovation

    • 21 Aug 2025
    • 9:28 AM
    • Online via Zoom
    Register

    This seminar will explore the multifaceted benefits of seaweeds (macroalgae) as powerful agents for human nutrition and sustainable agriculture. Rich in bioactive compounds, seaweeds are increasingly recognized as superfoods with high concentrations of essential nutrients — proteins, dietary fiber, polyunsaturated fatty acids, and micronutrients — offering promising solutions for global health and nutrition challenges.

    In addition to their dietary value, seaweeds serve as natural biostimulants in agriculture, promoting plant growth, enhancing antioxidant potential, enhancing resistance to stress, and contributing to soil health. Dr. Madhumi Mitra will highlight current research, practical applications, and future directions in the use of seaweed-derived products in the food and agriculture sectors.

    Dr. Madhumi Mitra is a tenured Professor of Biology and Environmental Sciences at the University of Maryland Eastern Shore (UMES), where she also serves as the Biology and Chemistry Education Coordinator in the Department of Natural Sciences. With a multidisciplinary background and over two decades of academic experience, Dr. Mitra has made significant contributions to teaching, research, and service in the fields of biology, environmental sciences, and STEM education.

    Dr. Mitra earned her Ph.D. in Botany from North Carolina State University, specializing in palynology, and holds two master’s degrees: one in Botany with a specialization in Phycology from Calcutta University, and another in Medical Cannabis Science and Therapeutics from the University of Maryland Baltimore. She also holds an Executive Education Certificate in Artificial Intelligence Strategy from Cornell University and an Online Teaching Certification from UMES.

    Her research spans a wide range of topics, including marine algae, sustainable bioenergy, and smart farming with emergent technologies. She has authored over 50 peer-reviewed publications, presented at numerous international and national conferences, and co-authored/edited two books — one on sustainable bioenergy with Springer and another on artificial intelligence with CRC Press. Her teaching philosophy emphasizes experiential learning, interdisciplinary collaboration, and innovation in the areas of biological and environmental sciences.

    Please join us for a 3 day adventure and canoeing trip to Smith Island, led by an experienced local sea kayaker. Come experience the magical and unique place that is Maryland’s only inhabited island archipelago. Step back in time to this island where people describe themselves as “living IN the water,” where fishing, crabbing, oystering and seafood are king, where birds (hopefully Pelicans!), wildlife and epic scenery abounds!

    All activities will of course be weather dependent. It can get windy at times. Rain should not stop us, so be prepared for it. It CAN be buggy at times, so insect repellent and long sleeve loose fitting clothing is recommended.

    Your Trip Leader is Dr. Gregory S. Pokrywka, MD, a Duke University graduate with a focus in Zoology and leader of Maryland’s most active sea kayaking group, the WatersEdge Kayak Club.. Gregg is an experienced ACA Certified Level 2 Trip Leader who has led hundreds of kayaking expeditions and day trips in multiple states, with the goals of safety, fun and adventure!

  • River chubs and Maryland's other little- known but fascinating native fish

    • 25 Sep 2025
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Maryland has a native freshwater fish fauna that is diverse and resilient. They are a critical part of our freshwater ecosystems. However, they remain understudied by scientists, underappreciated by most, and face threats from the modern world. Dr. Kemp will introduce the river chub (Nocomis micropogon) as an example of the complex role native fish have in the ecosystem and sum up 10 years of research on river chub nesting and their nest associate fish.  In addition, he will explain how you can experience the underwater wilderness of our freshwater streams!
    Stanley Kemp has been a professor at University of Baltimore since 2008. Prime research interests since being at UBalt include: native fish communities and how they are impacted by urbanization and climate change, stormwater control and watershed restoration, and box turtle conservation. His background is in Ecology, Evolution, and Environmental science and he holds degrees from Drexel University (BSc, MSc) and University of Pennsylvania (PhD).
