Biographical Sketch

Jeffrey Cornwell is a biogeochemist at the University of Maryland Center for Environmental Science, with interests in wetland restoration, sediment chemistry, reservoir biogeochemistry and the influence of bivalves on water quality.  Prior to his work at UMCES, he worked on arctic lake chemistry for his dissertation at the University of Alaska and marine sulfur chemistry at Texas A&M University.  Many of his research projects are interdisciplinary in nature, with cooperative programs funded in conjunction with microbiologists, physical oceanographers, geologists, geochemists, biologists and modelers.  In recent years, research has included work on denitrification associated with oyster restoration and aquaculture, the chemistry of dredged materials used for wetland creation at Poplar Island, the chemistry of lower Susquehanna River reservoirs, and wetland biogeochemistry.  Study locations have included numerous Chesapeake sites (Potomac, Choptank, Nanticoke, Sassafras and Corsica River, Susquehanna Flats, and Harris Creek oyster sanctuary.  Nationally, research has been carried out in Virginia, Puget Sound, Florida Bay, San Francisco Bay and coastal Maine.
