Ph.D., Ecology, Evolution, and Conservation Biology, University of Nevada, Reno, 2009

M.S., Biology, University of Nevada, Reno, 2003

B.S., Biology, Central Washington University, 2000

In addition to being a member of the Center of Excellence for Field Biology, my research involves investigating the diverse ways in which organisms interact with their environment. Most of the work that I do is at the interface between behavioral and physiological ecology. I also serve as the Curator of Herpetology in the David H. Snyder Museum of Zoology (Austin Peay State University). My personal website is https://cmgienger.github.io/
