Lab Personnel



Nicole with hatchling alligatorNicole White grew up in Birmingham, Alabama. She graduated from Birmingham-Southern College with a B.S. in Biology and a minor in Spanish. She became interested in herpetology after doing an internship working with loggerhead sea turtles in Tampa, Florida at the Clearwater Marine Aquarium. Since graduating, Nicole has served as a research coordinator at two sea turtle nesting projects in remote areas of Costa Rica and as an AmeriCorps Research Member at the Georgia Sea Turtle Center in 2012 and 2013. While she has worked primarily towards the conservation of sea turtles, Nicole has an avid interest in studying conservation and herpetology on a broader scale. Through field work and eventually graduate school, she hopes to better understand anthropogenic effects on wildlife and the environment, as well as educate the public on their impacts on the communities and ecosystems that surround them and what can be done to mitigate these impacts.

Sam with snakeSam Dean's herpetological future was sealed when, given three wishes in 1st grade, she wrote that she wanted "a mansion, 100 turtles, and $1,000,000" (the money was CLEARLY to fund all that turtle research, what foresight!). Sam graduated from Cornell University in 2012 with a B.S. in Natural Resources. As an undergrad she worked for Dr. David Bonter on Project FeederWatch at the Cornell Lab of Ornithology, where she grudgingly came to accept that birds might be cool. In 2011 she spent a summer interning at Jug Bay Wetlands Sanctuary, where she radiotracked eastern box turtles and worked on the Maryland Amphibian and Reptile Atlas (MARA). Post grad, Sam was a middle school substitute teacher, and in her off time used the Smithsonian collections to identify 2000 year old turtle bones from a Native American midden pile. She then headed to Archbold Biological Station to intern under Dr. Betsie Rothermel. Using motion-sensor cameras set up at tortoise burrows, she investigated the courtship and mounting behavior of gopher tortoises. Sam is interested in the life history and ecology of herpetofauna, social behavior and spatial ecology of turtles, and citizen science as a tool for public engagement in herpetology. Sam is joining the Tuberville Herpetology Lab and will be collaborating with Brett DeGregorio on a ratsnake telemetry project at Ellenton Bay.

Jacob with desert tortoise Jacob Daly is an incoming Masterís student at the University of Georgiaís Warnell School of Forestry and Natural Resources, under Drs. Tracey Tuberville and Kurt Buhlmann of SREL. He is a recent graduate of the University of Louisville, where he studied Biology and Ecology (B.S.). His thesis will focus on improving existing methods for head-starting Mojave Desert Tortoise hatchlings (Gopherus agassizii), in the effort to bolster recruitment in this threatened species. His study site is in the Mojave National Preserve, CA. Jacob first got involved with wildlife when he started volunteering at the Louisville Zoo at age 12. These early interactions with captive animals gave him a lasting passion for wildlife biology and conservation. As a junior in college, he began studying territorial behavior in fish, but his interest soon shifted to applied wildlife management and conservation. He then spent a summer as a technician on a large mammal project in New Mexico, assessing the effects of habitat restoration treatments on animal movements and habitat use. He has since gained additional wildlife experience mitigating bird-aircraft collisions. Jacob is interested in applied conservation, with specific interest in manipulative methods such as reintroduction, head-starting, and habitat restoration.

Chris will graduate from Warnell in December 2014 after which he plans to work seasonal jobs for a couple years before applying to graduate school.



Brett with snake Brett DeGregorio attended the University of Massachusetts at Amherst as an undergraduate and became very interested in the ecology and conservation of reptiles. After traveling around the United States working on various projects as a field technician he went back to school and earned his Masters degree at Indiana Ė Purdue University at Fort Wayne studying the spatial ecology and habitat selection of the massasauga rattlesnake. Shortly after graduating he was fortunate enough to spend some time on the SRS working with various SREL faculty including Drs. Tracey Tuberville and Kurt Buhlmann. When an opportunity arose that would allow him to pursue a PhD at the University of Illinois under direction of Drs. Jinelle Sperry and Pat Weatherhead while conducting his research on the SRS he jumped at the opportunity. He is currently conducting his 3rd of 4 field seasons studying snake Ė bird interactions at Ellenton Bay. Specifically he is interested in uncovering how snakes locate bird nests, what factors influence whether a nest is found by a predator or not, and how changing temperatures will alter the behavior of snakes and the trickle down effects upon their prey. Dr. Tuberville is hosting Brett's research and they are collaborating on a study investigating how time in captivity and rearing conditions affect foraging ability and post-release behavior in ratsnakes.


John with crocodile From a young age John Finger has always been interested in crocodilians and other animals. At North Carolina State University in Raleigh, NC, he studied Zoology, graduating in 2008, furthering that interest, and working on research projects investigating zebrafish endocrinology (HPA axis) and ecology (prey/habitat selection) of copperhead snakes. From 2006 to 2010, he worked as crocodilian handler with alligators (both species), many species of crocodiles, and a host of caimans (along with other reptiles, birds, and mammals) at Alligator Adventure in North Myrtle Beach, SC, developing countless questions about crocodilian biology and, in particular, immunology. These questions led him to the University of Georgia in the fall of 2010 to pursue in a PhD in Toxicology in the Department of Environmental Health Science under Dr. Travis Glenn. First, he began investigating infectious diseases, notably human and avian influenza, in American alligators. From May 2012 to May 2013, he was able to work as a research assistant on a saltwater crocodile farm for the University of Sydney in the Northern Territory of Australia. During his stay, he and his colleagues developed techniques to assess immunocompetence and determined some of the first measures of stress (and other hormones) in saltwater crocodiles, the latter of which has led to his interest of how multiple variables (including toxicants) may affect the HPA axis. His current project is centered on determining how toxicants (EDCs and metals) affect both the stress response and immune function in American alligators using in vivo tests and measuring alterations in RNA expression. John will be conducting several experiments at SREL in conjunction with Dr. Tracey Tuberville and her students.


Henry with tropical bird Henry Pollock is a 3rd year Ph.D. student in the laboratory of Dr. Jeffrey Brawn at the University of Illinois at Urbana-Champaign. He began birding a few years ago and fell in love, and has been conducting research on them ever since. Specifically, I am interested in how climate influences avian physiology. Currently, he is investigating whether or not tropical and temperate-zone birds exhibit differences in microclimate selection and metabolic responses to temperature, and is conducting comparative research between Panama and South Carolina. Henry and his colleagues are using techniques such as radio-telemetry and respirometry to address these questions. The data they collect will help elucidate how birds at different latitudes will respond to climate change and to environmental variation in general. Dr. Tracey Tuberville is hosting his research project, and they will be collaborating to collect pilot data comparing metabolic rates of reptiles in contaminated and uncontaminated habitats.
