Wally Fulweiler

Robinson W. Fulweiler

Associate Professor of Biology (jointly with Earth and Environment)

PhD, University of Rhode Island, 2007
Areas of Interest: Biogeochemistry and Marine Ecology

Current Research

My research is focused on understanding the impact humans have on marine systems. I am especially interested in how various scales of impact (e.g., local: nutrient loading and global: climate change) interact to alter fundamental ecosystem processes. As a biogeochemist and ecologist an overarching goal of my research is to answer questions about energy flow and biogeochemical cycling of nutrients (nitrogen, phosphorus, and silica), carbon, and oxygen in a variety of environments. Current research is centered on the transformations and the ultimate fate of nitrogen in the marine environment, the impact of climate change on benthic-pelagic coupling, silica cycling in salt marshes and estuaries, and greenhouse gas production in a variety of coastal environments.
