Nutrient cycling is the common thread that ties together our different research interests. We quantify the forms, biogeochemical transformations, and fluxes of essential nutrients for life on Earth, aiming to: (1) clarify important processes that underpin ecosystem function, (2) identify opportunities for beneficial intervention, and (3) design systems that achieve nutrient management objectives. We couple studies in the lab and field to explore the properties and responses of soils, sediments, plants, water, and residuals (organic & industrial) in engineered, urban, and agricultural ecosystems. To scale our nutrient dynamics work to the landscape, we use material flow analysis, modeling, and GIS.
Our work covers three important themes in nutrient stewardship: nutrient use efficiency in food systems, resource recovery and reuse, and nature-based solutions/green infrastructure.
My teaching in the Rubenstein School is focused on ecological design in the contexts of water quality, waste management, and food systems.
