John T. Lisle, Ph.D.

My research is focused on characterizing how microbes influence the geochemistry and carbon and nutrient cycling in surface water, ground water and coastal marine water and associated sediment systems thru the application of phylogenetics, microbial energetics and stable isotopes and radiolabeled substrates.
