In my lab we study biogeochemical cycles in terrestrial and marine ecosystems, with a particular emphasis on how naturally occurring perturbation and anthropogenic activities are impacting the transformations of Carbon and Nitrogen.
We use a combination of field and laboratory efforts and use stable isotopes as well as other state-of-the-art tools and equipment to understand processes in variety of environments ranging from headwater streams, large river, estuaries, marshes, and coastal oceans.
The lab’s research interests are broad and interdisciplinary, requiring collaboration with oceanographers, hydrologists, chemists, microbial ecologists, and plant physiologists. We are currently investigating the impact of oil spills on nitrogen cycling in nearshore marine ecosystems as well as the role of different marsh vegetation types on nitrogen cycling.
