Professor & Executive Director of Undergraduate and Graduate Programs, Civil and Environmental Engineering
Kelvin Gregory is a professor in the Department of Civil and Environmental Engineering. 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 goal of his research is to provide insight into the underlying science of enhanced engineering solutions for environmental challenges.
The research in Gregory’s lab is primarily experimental and applications-oriented as they apply to development of environmental technology. Current research projects include microbial ecology of agricultural plant tissues, water and sanitation in developing communities, and produced water from oil and natural gas development and CO2 sequestration.
In conjunction with the Center for Environmental Implications of Nanotechnology (CEINT) at Carnegie Mellon University, Gregory’s research group explores the interactions between bacteria and nanoparticles for an enhanced understanding of the fate, transport, and toxicity of nanomaterials.
He is the Faculty Advisor for the CMU Chapter of Engineers Without Borders and is interested in sustainable and appropriate water and energy technology for developing communities.
