Timothy R. McDermott
Professor; Ph.D. 1989, M.S. 1985, University of Minnesota; B.S. 1982, University of Nebraska-Lincoln. Soil & environmental microbiology, focusing on: microbe-metalloid interactions involving arsenic, selenium, and antimony; microbial ecophysiology and population genetics in geothermal environments. Techniques and methods used include fundamental molecular genetics, genomics and metagenomics, cultivation dependent and independent microbial ecology techniques.
