My research interests are in environmental chemistry and biogeochemistry. I evaluat

the response of ecosystems to disturbances, including air pollution, climate change and land disturbance. My research is largely field-based. However, I also use models as a research tool to understand the effects of ecosystem disturbance and as a management tool to evaluate ecosystem response to mitigation strategies. An important resource for the research program at Syracuse University is the Center for Environmental Systems Engineering (CESE), which includes state-of-the-art analytical equipment.

A principal research focus has been the investigation of effects of acid and mercury deposition and climate change on forest, aquatic and coastal ecosystems.  Much of my research on effects of air pollution on forest and aquatic ecosystems occurs in the Adirondack region of New York and New England.  Considerable research on the structure and function of forest ecosystems  and the response of ecosystems to disturbance occurs at the Hubbard Brook Experimental Forest in New Hampshire. I also work on ecosystem restoration, including Onondaga Lake in central New York, the Everglades in south Florida.

Some of my recent research themes are summarized on the left sidebar.
