Dr. Peter Dotray's research focuses on weed control and weed management systems. He holds a joint appointment between Texas Tech University, the Texas Agricultural Experiment Station, and the Texas Agricultural Extension Service. At Texas Tech, Dr. Dotray teaches undergraduate and graduate courses related to weed science and herbicides. At the Texas Agricultural Experiment, he has an active research program examining weed control systems in cotton, peanuts, corn, and a variety of other crops. During his career thus far, Dr. Dotray has secured over 190 externally-funded projects.

Dr. Dotray is a member of the Council for Agricultural Science and Technology, Gamma Sigma Delta, Phi Kappa Phi, the Southern Weed Science Society, the Texas Cooperative Extension Specialists’ Association, and the Weed Science Society of America. His past awards include induction into Who's Who Among America's Teachers (1998), admission into the Texas Tech University Teaching Academy (1999), and receipt of the following honors: Weed Science Society of America's Outstanding Young Weed Scientist Award (2004), Texas Tech University President’s Excellence in Teaching Award (2006), and Texas Tech University President’s Academic Achievement Award (2006).
