Biographical Information

Professor Felsot holds tenure in the Department of Entomology at Washington State University (WSU) and is also Affiliate Professor in the WSU School of the Environment (SoE) and the School of Biological Sciences (SBS).  Since 1993, he has been stationed in the WSU Food and Environmental Quality Lab in Richland, WA.   From 1978-1993, he was a project leader for pesticide chemistry and toxicology research in the Illinois Natural History Survey at the University of Illinois. 

Professor Felsot’s current responsibilities are divided among teaching, extension, and research.  He holds two part-time administrative positions at the WSU TriCities campus:  Graduate Coordinator for the Environmental Sciences Program in the SoE ; campus Program Lead for the Sciences. 

Current research activities have been focused on probabilistic risk assessments of environmental contaminants.  Professor Felsot also serves as specialist in environmental chemistry and toxicology for WSU Extension.  As Graduate Coordinator for the Environmental Sciences Program he oversees the progress of MS & PhD candidates toward successful completion of their degrees, as well as mentoring his own graduate students. 

During the 2000s Professor Felsot shifted his focus from laboratory- and field-based research to an expanded and intense involvement in teaching with responsibility for the following courses:  Introductory Biology; Introductory Botany; Biology & Society; Agricultural Entomology; Insect Physiology; Fundamentals of Environmental Toxicology; Applied Environmental Toxicology; Pesticide Toxicology; Pesticides in the Environment; Agricultural Chemical Technology for Crop Protection.  He is also involved with STEM (Science, Technology, Engineering, Mathematics) programs for middle school students, offering multiple insect biology workshops. 

Professor Felsot was a member of the Washington State Pesticide Incident Reporting and Tracking Panel (PIRT) and held the public toxicologist position on the Washington State Dept. of Agriculture Pesticide Advisory Board.  He was a member of the Advisory Committee for Crop Protection Chemistry of the International Union of Pure and Applied Chemistry (IUPAC).  He has served the American Chemical Society’s AGRO Division as Vice Chair, Program Chair, and Chair from 2003-2005.  From 1995-2007, he chaired the AGRO Young Scientist Research Recognition Award & Symposium and chaired for two years the AGRO New Investigator Award.  Professor Felsot received the American Chemical Society AGRO Fellow Award, the Entomological Society of America Founders Memorial Award, the WSU College of Agriculture Award for Excellence in Extension, Western Crop Protection Association North Star Award, Honorary Member Award of the WA State Weed Association, and the WSU College of Agriculture Team Interdisciplinary Award as a member of the Urban IPM & Pesticide Safety Education Team.  During 1992 he was a Fulbright Scholar assigned to lecturing and research in Cyprus.
