I am a biogeochemist and geobiologist interested in developing new tools to understand the processes that control carbon, nitrogen, and water fluxes through the Earth system. Theoretical aspects of my research include development of new tools to measure physical and chemical properties of the Earth, as well as applications of synthetic biology to Earth system questions. My applied research uses these tools to understand greenhouse gas removal processes, focusing on water, energy, agriculture, and marine processes. My group maintains an additional focus in the area of carbon market development in collaboration with the Baker Institute for Public Policy.
