Marine Biogeochemistry @ UD

I am a marine biogeochemist most interested in hydrothermal systems. I apply various molecular tools including compound specific radiocarbon, bulk isotopic, FTICR-MS, and GC-MS to study how carbon is transformed and cycled though microbial communities. My current projects investigate the bioavailability of hydrothermally altered organic carbon in both a high temperature, sedimented vent system (Guaymas Basin) and a cool crustal aquifer (North Pond). This past summer, I attend the International Geobiology Couse at PSU, where we got to spend two weeks in Italy studying caves, hot springs, and some rocks from the OAE! Originally from the Oregon Coast, I was an undergraduate at the University of Washington in Seattle. Outside of lab, I enjoy exploring the local outdoors, climbing, and playing in the community orchestra.

After studying the temperature records contained within stable oxygen isotope values in clam shells during my bachelor’s degree, I became interested in the use of stable isotopes as a way to understand biogeochemical processes. My master’s project here at UD focuses on the use of stable carbon and nitrogen isotopes to understand the sources and transformations of organic carbon within salt marshes and the lower Delaware Bay. Using bulk stable carbon and nitrogen isotope values as a proxy for organic matter sources, I hope to determine the significance of salt marsh vegetation to the organic matter within both sedimentary and particulate organic matter in the Delaware Bay. Outside of work I enjoy gaming, cooking, hitting the gym, and maintaining my freshwater shrimp tank.
