Dr. Osgood received his Ph.D. in Environmental Science from University of Virginia. His research has focused on natural marsh development on Mid-Atlantic and SE US barrier islands with an emphasis on hydrology, nutrient dynamics, and their influence on the developing plant community. His background also includes study of Phragmites and other non-native plant species and their impact on the marsh ecosystem. More recently, he has conducted research on the restoration of headwater streams and floodplain wetlands of coastal watersheds of the Mid-Atlantic US. He travels regularly throughout Latin America where he teaches and conducts research into conservation of natural resources in a cultural context. He serves as director of the environmental science program and teaches classes on issues in environmental science, principles of ecology, wetlands ecology, watershed hydrology, and Latin America and the environment.
