Jason E. Bruemmer is a Professor Emeritus in Colorado State University’s Department of Animal Sciences. He earned a B.S. in Animal Science and an M.S. in Reproductive Physiology from Texas A&M University, followed by a Ph.D. in Physiology from New Mexico State University. He joined CSU in 1996 and spent more than two decades teaching equine reproduction, reproductive physiology, and horse management. He also served as associate director of the Equine Sciences Program, President of the Equine Science Society, and as faculty adviser to the CSU Polo Club from 1998 to 2020. As a primary adviser, he guided 24 graduate students to the completion of 25 degrees. CSU recognized his teaching with the Charles N. Shepardson Faculty Teaching Award and the department’s Golden Boot Outstanding Professor Award.
Bruemmer now leads the Population Management Project at the USDA APHIS National Wildlife Research Center. His work focuses on fertility control for free-roaming horses and other wildlife, including research on GonaCon immunocontraception and vaccines targeting oocyte growth factors. His publications span equine reproductive biology and wildlife fertility management, and he has shared his research with scientific, veterinary, and land management audiences. He has been recognized by the American Society of Animal Science with the Equine Science Award in 2018 and, most recently, the Fellow Award by the Equine Science Society in 2025.
