I am currently an Associate Scientist at the Hudson River Foundation. Previously, I was a postdoctoral fellow at the University of Lethbridge. Broadly, my research focused on carbon cycling in freshwater and coastal ecosystems, using a combination of field-, lab-, and modeling-based methods. I am particularly interested in characterizing human impacts on aquatic ecosystems, especially as it relates to dissolved organic matter cycling, carbon transport between terrestrial and aquatic pools, and greenhouse gas emissions.
Originally from Brooklyn, NY, I attended Fiorello H. LaGuardia High School, majoring in fine arts. I completed my PhD at the Yale School of the Environment (YSE) in 2022, where I studied dissolved organic matter and iron cycling in the Connecticut River watershed. I received my B.S. and M.S. from CUNY City College of New York, where I studied Earth and Atmospheric Sciences. My Master's thesis examined the export of colored dissolved organic matter from Chesapeake Bay tidal marshes, and its subsequent photochemical and microbial degradation in estuaries.
