Expert Profile

Dr. Andrew Calinger-Yoak is a member of the core Anatomy and Physiology instructors at Otterbein and is responsible for the anatomy and physiology and the pathophysiology courses. His teaching experience includes perspectives from human medicine, evolutionary biology, as well as comparative anatomy. Calinger-Yoak’s research has taken him to India and Ethiopia to work on free roaming dogs as well as here in central Ohio working with raccoons. His passion for a particular brand of computer modeling, agent-based modeling, has let him work with a diverse range of academic and governmental partners on hugely varied projects. Before grad school, he worked as a Bear Ranger in Yosemite National Park.

Areas Of Expertise

  • Fertility Control in Urban Mammals
  • Disease Ecology
  • Computational Biology
  • Biology


Dr. Calinger-Yoak earned a Ph.D. from The Ohio State University in 2015 which focused on management strategies in wildlife populations. He uses veterinary, ecological, and computer modeling focused strategies to tackle complex problems. Through his experiences with agent-based modeling, he helped to create open-source projects that span the fields of veterinary medicine, ecology, mathematics, anthropology, and economics. In addition to academic research, he has taught many courses ranging from Introductory Biology to Human and Animal Physiology.
