Previous Research Projects
This page summarizes some of my previous research projects and collaborations, some of which continue to this day.
ADirondack Stream Food Webs
During the first summer of my PhD, I worked in the Adirondacks asking:
- How do abiotic factors including light, temperature, and pH, affect Adirondack stream food web structure?
- How does food quality in terms of fatty acid composition vary over the temperate growing season in an Adirondack stream?

HawaiIAN Anchialine Pools
During the first year of my PhD, I travelled to the big island of Hawai'i to study the ecology of anchialine pools with other student researchers from Cornell and UH-Hilo. We studied the feeding preferences, effect of food quality, and gut microbiome of Opae'ula (Halocaridina rubra) shrimp in the pools. This project is still ongoing with Nelson Hairston and Scott Santos.
Anadromous Fish And Land Use Change
In my undergraduate and Master’s of Environmental Science research in Professor David Post’s lab at Yale, I studied the ecological history of Connecticut’s coastal freshwaters. I used a combination of nutrient loading models and paleoecological analyses to understand how nutrient and community dynamics in Connecticut’s coastal lakes changed as anadromous alewife (Alosa pseudoharengus) populations declined and human land use in the region increased.
