Research Interests 

I am a biogeochemist and microbial ecologist with special interest in mercury. My group focuses on the microbial mercury methylation process in cultures, sediments and soils. Our research includes mercury fate and transport at multiple scales and in many types of environments, isolation and characterization of Hg-methylating microbes, the bioavailability of Hg for microbial methylation, and novel approaches to remediation of contaminated sites.
