coastal scientist | sensor enthusiast | shellfish admirer

In July 2017, I began a doctoral program in Marine Science at Stony Brook University (SBU) under the advisory of Dr. Chris Gobler. Presently, I am a 2019-2020 Science Training & Research to Inform DEcisions (STRIDE) fellow through an NSF-funded program at SBU.

I also worked for 5 years as a high school biology teacher in Brooklyn, NY, where I developed a passion for science communication, and became more deeply involved in issues involving the coastal ocean.

Broadly, I am interested in the symptoms of marine climate change (deoxygenation, acidification, and ocean warming) and the interactions with more direct human pressures such as nutrient overloading and eutrophication to drive coastal ecological and biogeochemical change.

Hypoxia & acidification

Across many coastal ecosystems, nutrient loading has lead to eutrophication, a subsequent draw down of dissolved oxygen and concurrent increases in carbon dioxide. These hypoxic and acidified conditions will likely intensify with continued climate change. My current research investigates the severity, persistence, variability, and physiological/ecological effects of co-occurring hypoxia and acidification in the coastal zone. Much of my research emphasizes the effects of these stressors on both ecologically and economically important organisms such as shellfish

Coastal change & restoration

Due to the anthropogenic activities of eutrophication, fisheries depletion, and climate change, coastal systems are in a time of unprecedented change and the fate of many important ecosystems is uncertain. In an effort to better understand these changing systems, a significant portion of my research focuses on ecological and/or biogeochemical functioning within degraded coastal systems, with an emphasis on refining restorative approaches and informing policy/management practices.
