My teaching and research interests are in the areas of environmental chemistry, biogeochemistry and water quality modeling. I teach undergraduate and graduate-level classes in environmental engineering, aquatic chemistry and biogeochemistry.
My research interests are in environmental chemistry and biogeochemistry. I have focused on assessing and quantifying the response of ecosystems to disturbances. The research is largely field-based. Models are also used 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 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 acidic 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.
