  • My research interests lie in how microbial communities and soil chemistry interact to affect ecosystem function. I use genomics and stable isotopes as my main tools. I have worked in a variety of ecosystems from the Australian Outback to permafrost-affected Arctic tundra. I am currently developing projects exploring how agricultural management affects microbial diversity and function in New Hampshire.
