Biosynopsis
I received my bachelor’s in Geosciences from Princeton and my M.S. and Ph.D. in Environmental Engineering from U.C. Berkeley. Prior to earning graduate degrees, I worked as a field engineer for Schlumberger and then as a research hydrologist for the U.S. Geological Survey. I conducted postdoctoral studies in Switzerland at the Ecole Polytechnique Fédéral de Lausanne as part of a multi-institutional research project sponsored by the US Department of Energy.
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 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.
I enjoy teaching courses in environmental sciences that bridge traditional disciplines and empower creative thinking to understand the nature and fate of contaminants and to engineer solutions. In particular, I am excited about areas relating to water treatment and reuse that incorporate my interests in environmental microbiology, geochemistry, remediation, and toxicology. I look forward to developing my research group at CSM and will be actively looking for new graduate students in 2009.
On the personal side, I am married to Melissa Sharp, a middle school science teacher. We have a three year old son, Jady and are expecting our second child this October. Though I grew up on the ocean and will always have salt in my blood, I’ve never had a bad day in the mountains. I enjoy all sports outdoors and have a particular weakness for backcountry skiing, biking, and climbing.
