I am interested in using my interdisciplinary background in marine biogeochemistry and physical oceanography to study how the ocean influences, and is influenced by, climate change. In particular, my research focuses on better understanding how humans alter coastal ecosystems. During my Ph.D., I developed a novel underwater mass spectrometer-based instrument to measure dissolved gases in coastal sediments. Over the 2022-23 academic year, I served as a Visiting Assistant Professor in the department. For my current postdoctoral research, I am investigating the natural variability of biogeochemical conditions in a Mid-Atlantic salt marsh ecosystem, as well as how marsh water quality and biogeochemistry respond to episodic events (e.g., storms and human dredging activities).
