Haley Larson, Ph.D., is a teaching assistant professor of animal health at Kansas State University's Olathe campus. She joined as a faculty member since August 2020. Prior to this, she was a senior scientist for Cargill Animal Nutrition and Health for four years.

In addition to her research role at Cargill, Larson led the company's agility leadership project. It aims to redesign how Cargill interacts with university students in the innovation space. The program will incorporate the perspectives from global campuses in Chile, the Netherlands, Norway and the U.S.

Larson instructs several graduate-level courses and serves as the major professor or as a supervisory committee member to graduate students in the veterinary biomedical science program at the Olathe campus.

She also designs academic courses and professional development programming tailored to Greater Kansas City's growing animal health industry.
