Director, Animal Resources & Campus Attending Veterinarian
Benjamin Weigler


Ben Weigler oversees the campus wide programs of animal welfare compliance, veterinary care, husbandry, and research support for animals used in teaching and research, and advisor to faculty programs in the appropriate and humane use of vertebrate animals to comply with university policies, federal laws, and contemporary standards of practice.

Before joining the University on June 1st, 2015, he served as an Associate Professor in the Department of Comparative Medicine and as an Adjunct Associate Professor in the Department of Epidemiology at the University of Washington, Seattle. Prior to that, he was a tenured Associate Professor in the Department of Companion Animal and Special Species Medicine for the College of Veterinary Medicine at North Carolina State University. For 10 years he served as the Director of Animal Health Resources at the world-renowned Fred Hutchinson Cancer Research Center in Seattle, WA, which is home to three Nobel Prize laureates in Physiology or Medicine. Concurrent with his academic appointments, he has 24 years of experience as a professional consultant for biomedical research enterprises throughout Seattle and other areas of the United States.

Ben is a nationally recognized research expert in several areas, including zoonotic disease epidemiology, occupational health and safety in animal research environments, applied biostatistics, and animal welfare compliance. He completed a preceptorship in pathology at the Smithsonian's National Zoo in Washington, D.C. and was a Fulbright research grant recipient to the University of Queensland, Australia where he studied the epidemiology of Chlamydia in free-ranging koala populations. While in veterinary school, he worked for the CDC's Division of Vector-Borne Diseases in Fort Collins, Colorado.

Ben is the recipient of numerous awards and honors, such as the Pravin N. Bhatt Scientific Investigator Award given by the American Association for Laboratory Animal Science, the National Outstanding Student Award given by the Conference of Public Health Veterinarians, the Maurice Shahan Award for the Study of Infectious Diseases at Colorado State University, Phi Zeta, Phi Beta Kappa, and several others. He has been an appointed member for two special topic committees at the National Academy of Sciences and as a Steering Committee member for the CDC's National Biosafety Symposium.
