As a microbial ecologist, I am interested in the organization of microbial systems, and how essential functions are coordinated and maintained over space and time. My research aims to achieve a fundamental understanding of microbial physiology, and opportunities to translate that knowledge into multi-disciplinary solutions for intractable environmental challenges.

Research Interests

  • Microbial ecology and physiology
  • Biogeochemistry
  • Systems Biology
  • Environmental Processes

Education and Credentials

  • B.S., Biology, University of South Carolina
  • Ph.D., Ecology and Evolution, emphasis Microbiology University of South Carolina

Affiliations and Professional Service
