Eric Roy

Eric Roy is an Associate Professor at the Rubenstein School of Environment and Natural Resources, University of Vermont, and Director of the Casella Center for Circular Economy and Sustainability. He is also a Fellow at the Gund Institute for Environment. His research focuses on nutrient cycling, biogeochemistry, and ecological engineering to design sustainable systems for nutrient management in food, waste, and water systems.

Education: Ph.D. in Oceanography & Coastal Sciences from Louisiana State University (2013), M.S. in Food, Agricultural & Biological Engineering from Ohio State University (2008), and B.S. in Mechanical Engineering from Old Dominion University (2006).

Research interests include nutrient stewardship, circular bioeconomy, and nature-based solutions. His work integrates lab and field studies with modeling to explore nutrient dynamics in engineered, urban, and agricultural ecosystems. Key themes include improving nutrient use efficiency in food systems, resource recovery, and green infrastructure design.

Teaching emphasizes ecological design in water quality, waste management, and food systems. His recent publications highlight advancements in phosphorus retention modeling, floodplain function analysis, and composting system optimization. He leads the Nutrient Cycling and Ecological Design Lab, advancing interdisciplinary solutions for environmental sustainability.
