Biography

I am an environmental microbiologist who studies how microbes control the fate of toxic metals in the environment. I combine molecular and meta-omic techniques with geochemical analyses to connect mechanisms across the cellular to community level to better understand ecosystem dynamics. My current research is primarily focused on mercury biogeochemistry.

I received my Ph.D. in 2017 from the University of Melbourne (Australia) in Earth Sciences with a focus in microbial ecology and genomics. From 2017 to 2020, I was a postdoctoral research associate at Oak Ridge National Laboratory exploring the biochemical mechanism of mercury methylation. Currently, I am conducting research at the Smithsonian Environmental Research Center as a Secretary’s Scholar in the Trace Metals and Microbial Ecology group.
