My lab focuses on the functional, morphological, ecological and evolutionary foundations of some behaviors of ectothermic tetrapods, particularly legless ones, like snakes. The behavior I have looked at most intensely is feeding behavior, but other maintenance behaviors, like drinking and locomotion, have also been examined. My primary interests lie in applying anatomical data to natural history and evolutionary problems. I am particularly interested in finding out how the highly specialized feeding apparatus of snakes has evolved. My research applies behavioral data to anatomy, basically using behavior to guide anatomical analysis. I do what I do because I like to watch living animals—both in the lab and in the field—and I have always been fascinated by animal structure and how it defines behavior. Most of the anatomical analysis is done at gross and microdissectional levels but histological data are also collected to answer specific questions when tissue organization becomes relevant.
Movement of my office and lab to smaller quarters in 2013 terminated my role as a graduate advisor. However, I still advise undergraduate research students. They explore a variety of functional and morphological projects, broadening my perspectives (and, hopefully, theirs as well), and periodically producing enough data for publication

Courses taught by Professor Cundall
BioS 121 - Core III: Integrative and Comparative Biology
Co-taught with Professor Itzkowitz
BioS 234 - Comparative Vertebrate Anatomy
A dissection lab is part of the course and counts for two credits of advanced lab.
