I'm a Ph.D. Candidate in the Department of Integrative Biology at the University of South Florida. I am interested in functional and evolutionary morphology, biomechanics, and physiological ecology, particularly with questions pertaining to reptiles and amphibians. For my dissertation I am studying the effect of temperature on feeding in chameleons (family Chamaeleonidae) in order to understand how explosively dynamic movements powered by elastic recoil are effected by temperature. Chameleons feed by way of ballistically projecting their tongue from their mouth to capture prey up to, and even over twice their body length. This highly specialized feeding mechanism utilizes an elastic storage mechanism, similar in ways to a bow-and-arrow, to launch the tongue. This recoil of elastic elements allows for extreme performance outputs far exceeding that of known muscle properties. My research has discovered that this elastic recoil also liberates tongue projection from much of the normal decrease in performance associated with muscle-powered movements at low temperatures, allowing them to feed at high performance, even at low temperatures where other sympatric lizard species remain inactive.
