Research Interests

Environmental concerns are a predominant theme for the 21st century as society realizes the importance of sustainability and resource conservation for our long-term health and prosperity. As an environmental engineer trained in combining molecular and microbiological tools with geochemistry, my research focuses on the applications and implications of biological processes that relate to water quality and reuse. I have applied my cross-disciplinary perspective towards investigating the bacterial degradation of emerging drinking water and biosolids-associated organics and towards understanding bacterially-mediated redox transformations of both metals and radionuclides. I am interested in bioremediation problems in natural waters and sediments and in drinking and wastewater.
