Bill Burgos is a Professor in the Department of Civil and Environmental Engineering at Penn State University. Bill received his PhD in Environmental Engineering from Virginia Tech. His research focuses on the biogeochemistry of metals and radionuclides and the bioremediation of organic contaminants. His research has focused on the biological reduction of iron oxides, iron-bearing clay minerals, and uranium in subsurface environments, and the biological oxidation of iron(II) and manganese(II) in mine drainage. He has recently begun conducting research on the environmental impacts of shale gas development. Bill is the Program Chair for the American Chemical Society’s Geochemistry Division.
