Patrick J. Tranel

Patrick J. Tranel received a B.S. degree, in 1990, in agronomy from Iowa State University, an M.S. degree, in 1992, in agronomy at Washington State University, and a Ph.D. degree, in 1996, in botany at Michigan State University. After a one-year postdoctoral with Monsanto Company in St. Louis, Mo, Dr. Tranel joined the Department of Crop Sciences at the University of Illinois in Urbana-Champaign. He was hired specifically to take a molecular biology approach to weed science, and currently is an Associate Professor of Molecular Weed Science. A major research emphasis is to understand mechanisms and evolution of herbicide resistance in weeds. He has conducted substantial research on resistances to acetolactate synthase (ALS)-inhibiting herbicides, protoporphyrinogen oxidase (PPO)-inhibiting herbicides, triazine herbicides, and glyphosate. His research has spanned a variety of weed species (e.g., Xanthium strumarium, Kochia scoparia, Ambrosia spp., Setaria spp.) but a primary focus has been the weedy Amaranthus species (pigweeds), particularly waterhemp (Amaranthus tuberculatus). In addition to herbicide resistance, his research interests include genetic diversity in weed species and development of genomic resources for weed science research.
