Postdoctoral Fellow
I am working on the ENIGMA project, where we study subsurface microbial communities and the environmental processes that they carry out. I am currently studying nitrate-reducing bacteria isolated from a contaminated field site. My goal is to create synthetic consortia composed of the isolates in order to address environmentally relevant questions about nitrate reduction and microbial ecology. While I am still getting started, future goals include developing assays to probe resilience as well as studying microbial assembly and specialization in evolved nitrate-reducing communities.
