Current Research
My research couples applied and fundamental approaches that use microbes as part of sustainable environmental clean-up strategies. A key part of my research examines how microbes control the fate of pollutants and critical materials in contaminated habitats. My team combines microbial physiology, genetic manipulation, metabolite analyses, and whole-community sequencing to answer our research questions. We work closely with industry and government partners to study the biogeochemistry of electronic waste, landfills and contaminated groundwater systems. Currently, we focus on studying metals, plastics, and have expanded to tackle “forever chemicals” such as PFAS. Our goal is to translate our findings into sustainable waste reclamation strategies that protect environmental and human health.
