I teach courses on energy and sustainability in the Environmental Studies Department at SJSU. My research focuses on the social and environmental dimensions of energy systems. In particular, I am interested in the intersection of innovation, emerging technologies and environmental justice in the life cycles of energy from solar, biofuel, and natural gas. I study how metrologies, institutions and nature shape clean energy commodity chains and co-produce socio-environmental outcomes. My areas of interdisciplinary specialization include political ecology, science & technology studies, and life cycle assessment. I am a member of the American Association of Geographers, the Society for the Social Studies of Science, and the Association of Environmental Studies and Sciences. In a prior career, I worked for a bioremediation startup as a project engineer at MTBE spill sites, and before that I was a chemical process engineer for a Fortune 500 chemical manufacturer. I've done energy and environmental consulting work for the Sierra Club, EDF, and numerous biofuel companies with a team at EcoShift.
