Biographical Sketch:
My major research interest has been on the cycling of elements in the environment, especially the biogeochemistry of nitrogen, sulfur, iron, and phosphorus. Much of my work has been focused in soils and sediments where element cycling takes place under different conditions of oxidation and reduction. A major theme of my research has been to examine how sediment processes either ameliorate or augment the effects of anthropogenic inputs of elements to ecosystems. For example, I have worked on topics such as the effects of acid deposition on the sulfur cycle of lakes, the mobility of trace metals in salt marsh sediments, the controls on the availability of phosphorus in tundra soils (Arctic LTER), and the controls of denitrification in marine and lake sediments. Much of my current research is examining how increased nitrogen inputs, hydrologic disturbances, and sea-level rise are altering nitrogen and carbon cycling in estuaries in the Plum Island marsh system (PIE LTER) north of Boston. I am also investigating the controls on nitrogen removal pathways in places ranging from the New England continental shelf to arctic lakes on the north slope of Alaska.
