I am interested in both fundamental questions in microbial ecology as well as the application of unique microbial species for bioremediation. There are three major areas of interest in my lab:1) the ecophysiology, biochemistry, and molecular biology of dissimilatory metal reducing bacteria, 2) the ecophysiology of phototrophic prokaryotes and 3) the environmental impacts and microbiology of unconventional shale gas extraction. In the first area, I am investigating the reductases and electron transport system of several dissimilatory metalloid reducing bacteria. Respiration using alternative terminal electron acceptors such as arsenic and selenium oxyanions is a relatively new discovery. Ongoing studies include the characterization of the arsenic metabolism in the chemolithoautotroph Alkalilimnicol ehrlichii, selenium oxyanion reduction by Bacillus selenitireducens and Sulfurospirillum barnesii, and the biotransformation of inorganic arsenic and organoarsenicals.The second area involves research on community structure and biogenesis of modern marine stromatolies in the Bahamas and Shark Bay, Australia. The third area involves well water quality testing, GIS base mapping, and microbiological testing of fluids associated with Marcellus shale. The lab is currently funded by grants from the Heinz Endowments and Colcom Foundation.
