He teaches Environmental Microbiology for Engineers, Fluid Mechanics and Fluid Mechanics Laboratory. His research interests lie in environmental biotechnology and biogeochemistry with a focus on the fundamental interactions between microorganisms and geochemistry which influence the fate of environmental pollution. The research in his laboratory is primarily experimental and applications-oriented as they apply to development of environmental technology. Current research projects include development of electrode-based remediation of radionuclides and contaminated sediments, management of produced water from unconventional oil and natural gas development, and biogeochemistry of CO2 sequestration.
