Dr. Chadwick Hanna
- B.S.: Cumberland University
- M.S.: Middle Tennessee State University
- Ph.D.: University of Louisville
Dr. Hanna recently finished his Ph.D. At Cal U, he teaches various animal anatomy and physiology classes. His research tends to focus on the physiological and behavioral ecology of invertebrate animals, specifically spiders. In the past, he has examined how environmental temperatures influence where female spiders lay their eggs. More recently, he has examined how factors such as body color and the presence of conspecifics affect where juvenile spiders choose to forage.

Dr. Hanna's research generally focuses on understanding what factors, or things, influence where animals live. His primary study animals are spiders, and he generally examines how physiological and behavioral factors affect the site choices of these animals.
Student Research Projects
Dr. Hanna has mentored students examining the differences in pairing behavior in winner and loser cichlid fish. The fish are territorial, so the male will tend to take over the territory (winner male), and the other male gets pushed out (loser male).

"The best part of my job is seeing when that light bulb goes on in my students' heads when they suddenly ‘get' what we have been talking about. Sometimes it can be very frustrating to both the teacher and the student along the way, but when students master a difficult concept in my classes, it always reminds me why I have the best job out there."
