Professor — Biology
Ph.D. Saint Louis University, 2011
I have extensive experience in research on the reproductive biology of amphibians and reptiles. Such research includes primarily the urogenital morphology of salamanders and squamates but also includes projects on sperm morphology/physiology, the morphology of secondary sexual characteristics, the evolution of reproductive cycles, and the odd morphological inquiry into fishes.
I was mentored by renowned herpetologists Robert D. Aldridge and David M. Sever during graduate school.
I am currently a Professor of Biology at Southeast Missouri State University in the Department of Biology.
In my free time, I enjoy fishing, kayaking, photography, playing softball, hiking, biking, working on Jeeps, playing with cats, and watching football and baseball.
