Aaron Krochmal

Associate Professor of Biology
  • B.S., Biology, Union College (NY), 1996
  • M.S., Biology, New York University, 1998
  • Ph.D., Ecology and Systematics, Indiana State University, 2003

I am a broadly-trained, integrative organismal biologist interested in the behavior, physiology, and ecology of reptiles. Specifically, I combine these disciplines to investigate how reptiles perceive, interact with, and navigate their environments. 

  • General Biology I and II
