  • I am a biogeochemist interested the ways in which the evolution of life on Earth and the evolution of the Earth`s environment have affected one another over the course of Earth history. Our laboratory uses the tools of organic geochemistry to try to understand how organic structures synthesized by living organisms can be preserved over geological time spans, and record information about the organisms and ecosystems from which they derive. We also use light stable isotope geochemistry to try to understand characteristics regarding the biogeochemical cycling of carbon, hydrogen, nitrogen, oxygen, and sulfur.
