Education

  • Ph.D., Ecosystem Science, University of California, Berkeley, 2016
  • B.A., Environmental Earth Science (high honors), University of California, Berkeley, 2005

Research Interests

My research focuses on identifying and quantifying geochemical and biological processes using stable and radioisotope analyses of organic and inorganic material. Specifically, I am interested in the interactions between climate, minerals, and microbial communities in soil and sediment environments, and how these interactions scale up to the landscape level.
