I am currently a post-doctoral fellow in Dr. Matt Bogard's lab at the University of Lethbridge. Broadly, my research focuses on carbon cycling in freshwater and coastal ecosystems. I am particularly interested in characterizing dissolved organic matter (DOM) cycling and transport between terrestrial and aquatic pools and its linkages to greenhouse gas fluxes. I utilize a combination of field- and lab-based methodologies, such as DOM optical measurements, PARAFAC modelling, and radiocarbon.
Originally from Brooklyn, NY, I attended Fiorello H. LaGuardia High School, majoring in fine arts. I did my PhD with Dr. Pete Raymond at the Yale School of the Environment (YSE), where I studied dissolved organic matter and iron cycling in large rivers. 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.
