I am an Associate Scientist at the Hudson River Foundation. My research as a postdoctoral fellow and as a graduate student 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 related 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.

Exploring the Depths of Water's Role in Climate Change

Aquatic ecosystems play an essential role in the greenhouse gas emissions cycle. Water bodies can sequester carbon – and they can also release emissions. Reducing these emissions and exploring ways of increasing their potential for carbon uptake is at the center of new climate research at YSE.

New Haven Promise Inspires New 'Champions' for the Environment

For Johnae McArthur, a University of Connecticut undergraduate and one of five New Haven Promise interns at F&ES this past summer, the experience was more than just a crash course in biogeochemistry or a chance to explore the woods near her hometown. It also set her on a new career path.
