Research Technician

Seth Berger

Seth Berger received a B.S. (2014) in Chemistry and Environmental Studies from the University of Wisconsin- Madison. His interests in water chemistry and analytical instrumentation brought him to work as a technical support chemist at SEAL Analytical in Milwaukee. As a specialist on segmented flow auto-analyzers, he travelled to perform installations and trainings at a variety of environmental laboratories across North America. He hopes to eventually pursue a Ph.D. in Biogeochemistry.

Postdoctoral Associates

John Angell, Postdoctoral Associate

Dr. John Angell graduated cum laude with a B.S. in Biology from the University of Massachusetts – Amherst in 2006 and received his Ph.D. from the University of Massachusetts – Boston in 2016. Prior to his graduate work, he worked as a field/lab technician in the Sala Lab at Brown University. As a microbial ecologist, John’s research focuses on using molecular tools to understand the factors that control the community structure and function of microbes in the environment with a particular emphasis on microbes involved in the nitrogen cycle. John’s dissertation research, under the direction of Dr. Jennifer Bowen, investigated the role abiotic conditions play in structuring microbial communities in salt marsh sediments at very fine spatial scales. While at UMass Boston, he received a Sanofi-Genzyme Research Fellowship in 2014 and several graduate teaching awards. John is currently a Postdoctoral Faculty Fellow at Boston University where he will both teach and work in the lab. In the Fulweiler Lab, John will apply molecular techniques to explore the biological underpinnings of the geochemical transformations measured in coastal systems.

Graduate Students

Alia Al-Haj

Alia Al-Haj received a B.S. (2010) in Biology and M.S. (2014) in Environmental Sciences from the University of Virginia. Her Master’s thesis investigated the effects of changes in light and temperature on eelgrass depth limits in the Virginia Coastal Bays in order to identify areas for future eelgrass restoration. Her Ph.D. research is focused on quantifying blue carbon capabilities of seagrasses. She is particularly interested in fluxes of carbon dioxide and methane from eelgrass beds and how these fluxes change under excess nutrients.

Emily Chua, Ph.D. Student

Emily Chua received a B.Sc. Combined Honours in Physics and Oceanography and a minor in Math from Dalhousie University (Nova Scotia) in 2015. Her honours thesis investigated wave-current interactions in tidal channels, with applications to tidal energy. During various research internships during her undergraduate degree, she investigated charge transport in hybrid solar cells (2013; University of Konstanz, Germany), and developed a deep sea membrane inlet system for use with an underwater mass spectrometer (2014; Woods Hole Oceanographic Institution, MA). In 2015, Emily moved to Boston to begin her Ph.D. at Boston University (BU) with a Fulbright Canada Student Award. In her first year at BU, she received a National Sciences and Engineering Research Council of Canada (NSERC) Scholarship. For her dissertation she is working on an NSF funded project to develop a novel underwater mass spectrometer for measuring biogenic gases in permeable sediments. This project is in collaboration with SRI International (St. Petersburg, FL) and Skidaway Institute of Oceanography (Savannah, GA).

Hollie Emery, Ph.D. Student

Hollie Emery graduated with a B.S. in Biology from the University of Massachusetts, Boston in 2009. While there, she completed a senior thesis examining the interactive effects of altered precipitation and warming on soil moisture at the Boston-Area Climate Experiment. After graduating, she continued working at the BACE as a research assistant, and extended her soil moisture research by relating it to changes to plant communities. Hollie is now a Ph.D. student at BU, where she has been investigating how human impacts (e.g. tidal restriction and restoration, invasive species, and precipitation change) alter greenhouse gas fluxes in salt marshes. She has also ventured to Puerto Rico to work with Brita Jessen (a Ph.D. student at GSO/URI) on her mangrove nitrogen fertilization experiment. While at BU, Hollie has received the National Park Service George M. Wright Climate Change Fellowship, the Joshua A. Nickerson Conservation Fellowship, and the NSF Doctoral Dissertation Improvement Grant to study the effects of precipitation intensification on salt marsh carbon sequestration and nitrogen removal processes

Sarah Foster, Ph.D. Student

Sarah Foster earned a B.A. (2006) in Ecosystems Ecology and Environmental Science at Hampshire College and a M.A. (2012) in Earth Sciences at Boston University. In between her undergraduate and graduate work Sarah spent four years working on a long-term water quality project in San Francisco Bay as an estuarine research assistant for the US Geological Survey. In her Masters research at BU, Sarah investigated the spatial and historic variability of sediment nutrient cycling and denitrification in Waquoit Bay, MA. Sarah’s fundamental scientific interest is the exploration of coastal ecosystem response to anthropogenic changes (such as nutrient pollution and climate change) across a variety of geographic and temporal scales. Sarah is currently pursuing a Ph.D. and her research is focused on the impacts of low oxygen on the microbial flux of nitrous oxide and methane. She was recently awarded the National Defense Science and Engineering Graduate fellowship in support of this research. During the summer of 2013 Sarah had the opportunity to study microbial oceanography at C-MORE at the University of Hawai’i Manoa. Check out her blog of the course. When she’s not doing her own research Sarah also enjoys teaching and participating in outreach programs. For the past three years she has led a workshop called “Microbes and Mud” for middle school girls as part of the Women in Science summer program at the Waquoit Bay National Estuarine Research Reserve.
