Dr. Sasha Tetzlaff earned his PhD in Natural Resources and Environmental Sciences from University of Illinois, MS in Biological Sciences from Purdue University, and BA in Environmental Studies from Florida Gulf Coast University.

His research interests broadly encompass wildlife ecology and behavior. This has led to field and laboratory studies focusing on movement and space use, habitat selection, physiology, foraging, wildlife diseases, captive animal welfare, reintroduction biology, animal personality, and predator-prey interactions. An overarching goal of his research is to integrate multiple disciplines to inform wildlife management and conservation issues.

Although Dr. Tetzlaff has studied numerous animal species, much of his work has focused on reptiles (primarily snakes and turtles). He thoroughly enjoys teaching and mentoring diverse students and helping them achieve their educational and career goals. Aside from working in academia, Dr. Tetzlaff  has been a biologist for the US Army Corps of Engineers and an educator and animal caretaker at multiple zoos.
