David is a marine biogeochemist with over 20 years experience in marine and freshwater studies related to nutrient cycling, isotope biogeochemistry, and wetland nutrient and metal geochemistry. He started as an organic geochemist studying the transport of organic compounds in estuaries and from atmospheric transport, and shifted to studies of sulfur and selenium geochemistry. He has published studies related to many aspects of biogeochemistry and has a broad range in the cycling of bioactive elements. David has a B.S. in Oceanography from Florida Institute of Technology and a Ph.D. in Chemical Oceanography from Old Dominion University.

| Dr. Bhanu Paudel, Ruth Patrick Post Doctorial Scholar
215-299-1171
bp425@drexel.edu
Bhanu is interested in hydrological processes, sediment-water interactions, and trace element cycling in lotic and lentic ecosystems. His current interests include understanding the impact of climate variability on aquatic resources. Bhanu has studied nutrient biogeochemistry at sediment-water interface in Texas and New Jersey estuaries. He also uses statistical modeling technique to understand the roles of environmental parameters in lotic and lentic ecosystem. Bhanu received his B.S and M.S in Environmental Science from Tribhuvan University and earned his Ph.D. in Coastal and Marine System Science from Texas A&M University-Corpus Christi.
