Gerald K. Sims

Gerald K. Sims is a microbiologist with expertise in environmental applications of bacterial physiology. He holds degrees from McNeese State University, Louisiana State University, and Purdue University. Over the years, Dr. Sims has published many papers on mechanisms of biodegradation, factors controlling biodegradation in situ, and the ecology of organisms involved in important soil processes. He has served in the faculty at the Ohio State University, was a Project Leader at Dow Chemical Company, and in 1992, joined the USDA-ARS at Urbana, Illinois, where he is presently the Research Leader of the Invasive Weed Management Unit. He holds adjunct faculty appointments with the University of Illinois in the Department of Natural Resources and Environmental Sciences and the Department of Crop Sciences and is a member of the Graduate Faculty. Dr. Sims recently served as an Acting National Program Leader for Crop Protection and Quarantine, USDA-ARS, and as the Acting Deputy Director for the four USDA-ARS Overseas Biological Control Laboratories. Dr. Sims has been a member of the Society for Environmental Toxicology and Chemistry, the Soil Science Society of America, American Society for Microbiology, and the American Chemical Society, and has served in a variety of capacities for these societies. Over the years, he has mentored more than 20 graduate students and postdoctoral fellows, and provided services to professional organizations and in the editorial aspects of publishing scientific literature in numerous journals, books, and online media.
