Research Interests:

Developmental genetics; Reptile and amphibian husbandry; Effect of egg incubation temperature on life history traits; Impact of using live reptiles on students' interest in science and attitudes toward nature.

My research focuses on improving husbandry of the species maintained in the BGSU Herpetarium, including analyses on the effect of egg incubation temperatures on life history traits in reptile, primarily geckos. We are observing the effect of egg incubation temperature on sex ratios, hatch rate, early growth rates, female fecundity and lifespan. Other projects include analyzing the effect of water quality on tadpole development in poison dart frogs (Dendrobates sp.), and the genetics of color variants in the pictus gecko (Paroedura pictus) and the inheritance of pattern in corn snakes (Elaphe guttata). Students in the lab learn husbandry requirements of a variety of reptiles and amhibians and are encouraged to design their own projects. Animals in the Herpetarium are also used in classroom demonstrations for grades 1-12, as well as several college classes. Another research interest being developed is the impact of using live reptiles on students' interest in science and attitudes toward nature.
