John received his BS in Biology from the University of Texas-Austin. As an undergrad, he worked with Dr. Melissa Kemp on projects that examined morphological variation in Ambystoma salamanders and Phrynosomatid lizards, as well participated in general herpetofauna surveys in central Texas. After graduating, John worked as a field technician at Texas A&M, working with species such as Houston toads and chicken turtles. For his thesis, John will be investigating how variation in food web structure impacts pond-breeding salamanders. John is also participating in the Watershed Scholars program while at SIUE.
Jessica Sandoval (2021-2023)
Jessica obtained her BS from the University of Central Florida. As an undergrad, she assisted on several research projects, including work with bats, wetland biogeochemistry, and gopher tortoises. Post-graduation, she worked as a field technician for the USFS. Most recently, Jessica was a wildlife technician for the Longleaf Alliance, where she worked with the endangered Reticulated Flatwoods Salamander.
Jessica's MS research focused identifying different factors that affected rates of paedomorphosis and delayed maturation in mole salamanders in natural ponds. She now works for the Washington Department of Natural Resources.

Mariah Mack (2021-2023)
Mariah graduated from Penn State-Behrend with a BS in Biology. While there, they worked with Dr. Lynne Beaty on a variety of amphibian projects, including dorsal coloration patterns in American Toads, which was published in 2021 in the Journal of Herpetology. After graduation, they spent a year as an intern at the Memphis Zoo, where they worked on husbandry of Dusky Gopher Frogs and gamete cryopreservation in Fowler’s Toads.
Mariah's MS research tested how hydroperiod and non-consumptive predator effects influenced small-mouthed life history.
