Biography

Dr. Groffman's research focuses on microbial processes in an ecosystem context. His objectives are to gain insight into 1) the role that microorganisms play in ecosystem functions related to nutrient cycling, water and air quality and soil carbon storage and 2) environmental regulation of microbes. Developing conceptual and practical ecosystem contexts for this work has required a large number of study sites and strong collaborations with other scientists.

Education

  • PhD, Ecology, University of Georgia, 1984
  • BA, Environmental Science, University of Virginia, 1980
