Research Interests

Microorganisms have been key drivers of environmental change throughout most of earth history. They are responsible for oxygenating the atmosphere, driving carbon, nitrogen and other element cycles, and through their roles in food production, disease, and more, are of fundamental importance to modern human societies. As a result, developing a quantitative understanding of how microorganisms interact with their surroundings is essential to explaining earth history, forecasting the impact of climate change, and, on a more fundamental level, understanding the origin, extent and limits of life. Within this context, the goal of my research is to determine how environmental forces affect microbial activity and how microorganisms influence geochemical cycles. Towards this end, I develop and apply computational models to diverse biogeochemical systems in collaboration with microbiologists, oceanographers and geochemists who are involved in field and laboratory studies concerning life at the fringes.

Specific Research Areas:

  • Theoretical Biogeochemistry
  • Reaction Transport Modeling
  • Experimental Biogeochemistry
  • Bioenergetics
  • Organic matter degradation 
  • Biogeography           
  • Thermodynamic data development
