Sawyer graduated from Brown University with an Sc.B. in Environmental Science and recently finished a two-year appointment at the U.S. Environmental Protection Agency as an Oak Ridge Institute for Science and Education fellow, where he investigated the biogeochemical responses of estuaries to climate change and managed nitrogen reductions. Funded by the NSF Graduate Research Fellowship Program, Sawyer is working to measure benthic gas fluxes through the development of an in-situ underwater mass spectrometer. If you can’t find him in the lab, he's probably sailing in the North Atlantic with his family.

Drew graduated from Boston University with a B.A. in Earth and Environmental Science and a minor in Marine Science in 2024. He grew up in Gloucester, Massachusetts with a deep love for the ocean and the ways that humans interact with it. Drew has previous experience researching bottlenose dolphins in the Mediterranean Sea and nature-based infrastructure solutions in East Boston. Now working as a research technician in the lab, he will research net nitrogen removal at natural and restored oyster reefs across the northeastern United States. Outside of the lab, Drew spends his time cooking, fishing, and exploring the North Shore of Massachusetts on his boat.

Lena is postdoctoral fellow, funded by the BU Society of Fellows program. She received her doctorate at the Academy of Natural Sciences of Drexel University in Philadelphia, where her dissertation examined estuarine water quality including eutrophication over decadal to millennial scales using biogeochemical proxies in sediment cores and historical shells. During her postdoc, her interdisciplinary research will investigate spatial and temporal patterns of C sequestration in salt marshes and apply her love of using art in science communication about urban marshes. You can learn more about her past and current research at her website.

Description goes hereTeaghan graduated from Oberlin College in 2025 with a B.A. in Geology and in Environmental Studies. Her prior research has focused on nutrient cycling in aquatic systems; she has worked on Martha's Vineyard monitoring water quality and cyanobacteria, in Ohio investigating sources of phosphorus in Lake Erie, and in The Bahamas determining the impacts of Hurricane Dorian on inland aquifers. She grew up among New England's Great Salt Marsh and is happy to be back in the coastal ecosystems that raised her. She is excited to join the lab as a visiting fellow assisting with PEARL and oyster denitrification research.

Subhadeep is a Boston University microbiome postdoctoral fellow, co-mentored by Prof. Daniel Segrè. He completed his Ph.D. in Oceanography at the Mediterranean Institute of Oceanography (MIO), Aix-Marseille Université, France. His doctoral research contributed to unraveling the intricate relationships between biogeochemical and physical factors shaping diazotroph activity and diversity in the Indian Ocean. During his postdoc, he will investigate the relationship between sediment microbial communities and their biogeochemical functions, with the aim of translating this knowledge into a predictive sediment metabolic model.

Mel received a B.S. in Biology from the University of Arkansas at Little Rock and a M.S.  in Marine Science from the University of Maryland College Park. Her graduate research at the Chesapeake Biological Laboratory focused on the transfer of biomarkers in a marine food web. Upon graduation, she worked at the Virginia Institute of Marine Science where she was involved in research using biomarkers as indicators of organic matter in the Sacramento-San Joaquin River Delta. Most recently she was a research associate at the University of West Florida where she participated in projects measuring polycyclic aromatic hydrocarbons related to the Deepwater Horizon oil spill in the Gulf of Mexico. Melissa has extensive experience with a variety of analytical instruments such as Nutrient AutoAnalyzer, GC, GC/MS, and HPLC.

Michelle is a postdoctoral fellow at Boston University, where she is working to understand the impact of coastal sediments on carbon and nutrient cycling through an NSF ULTRA-Data project. She also leads an NSF Macrosystems Biology project to investigate relationships between nitrogen and oxygen flux in streams across ecoregions. In 2024, she completed her Ph.D. in Biology and a Graduate Certificate in Data Science at Michigan Technological University, where her dissertation research investigated the interactions between energy and nitrogen cycling in streams. Outside of lab, you can probably find her darning the holes in her socks.

Lili is a sophomore Research Intern working towards a B.A. in Earth and Environmental Sciences and minors in Marine Science and Comparative Literature. She grew up in South Florida, which has fostered a deep love and appreciation for oceans, nature, and the environment. Lili has had previous experience researching marine sediment and global temperature fluxes, though she is excited to learn more about biogeochemical cycles and the anthropogenic impacts on coastlines. Outside of the lab, Lili enjoys hiking, photography, and growing her rock collection. 

Cat graduated from Maine Maritime Academy in 2021 with a B.S. in Oceanography. During her time at MMA, she completed a Research Experience for Undergraduates (REU) at the Bigelow Laboratory for Ocean Sciences, investigating alternative phosphorus sources for open ocean phytoplankton. She was also a recipient of the NOAA Ernest F. Hollingsscholarship and was a data analytics intern for the NOAA Pacific Marine Environmental Laboratory, researching methane sources in Puget Sound. In the fall of 2023, Cat will be transitioning her role within the lab from technician to student to pursue her PhD. Cat is interested in the nitrogen cycle, from nitrogen fixation to DON. Outside of the lab, you can find her reading sci-fi/fantasy or enjoying a walk along the Charles.

Description goes hereJonas is a freshman Research Intern in the Fulweiler Lab and is working towards a Bachelor of Marine Science in CAS with a minor in Business Management at Boston University. Originally from Los Angeles, California, his passion for the ocean was built on a foundation of surfing, diving, and marine conservation work. Before joining the lab, Jonas served as a Senior Aquarist with Heal the Bay, where he managed shark tanks, educated visitors, and collected samples for a global eDNA research project. He also interned at Bleu World, utilizing his Master Scuba Diver certification to support behavioral research on the critically endangered California Seabass. Additionally, Jonas has a strong interest in understanding how environmental shifts impact coastal ecosystems, having previously authored a research paper examining the effects of climate change on mole crabs. Outside of his research and coursework, Jonas is a proud Eagle Scout who loves spending his free time surfing and scuba diving.

Zach is a recent graduate from Middlebury College with a B.A in Biology and Environmental Studies. He grew up on Martha’s Vineyard, Massachusetts where he spent every summer on the water kayaking, sailing, and swimming. Zach has had previous research experience in both marine and freshwater ecosystems: researching shellfish, larval fish, and stream macroinvertebrates. He joined the lab as a technician in June of 2026 and is excited to continue developing his knowledge of biogeochemical cycles in coastal marine systems. Outside of the lab Zach enjoys exploring nature via running, cycling, kayaking, and birdwatching.

Emily graduated from Lafayette College in 2022 with a B.S. in Biology and a B.A. in Environmental Studies. She is interested in studying coastal resiliency and specifically researching how different anthropogenic forces and coastal restoration methods impact the biogeochemistry of salt marshes. Funded by the NOAA Margaret A. Davidson Fellowship, Emily is currently studying how sea level rise-driven vegetation shifts and die-off are impacting salt marsh greenhouse gas fluxes.
