I am an ecological physiologist with interests in maternal provisioning of resources to offspring, temperature-dependent sex determination, and the development of the immune system in reptiles. Studies in my lab involve the integration of both laboratory and field work to explore how maternally-mediated ecological and physiological parameters act and interact to influence parent and offspring phenotypes. More recently we have focused on how thermal fluctuations affect offspring phenotype.
I collaborate with Dr. Laura Vogel (ISU) on the immunology projects and Dr. Ryan Paitz (ISU) on the sex determination projects.
The lab is currently focusing on questions such as:
- How does the incubation environment (temperature, steroids, etc.) affect offspring phenotype? How does the incubation environment affect the expression of genes associated with gonadal development?
- Do yolk steroids alter sex determination in species with environmental sex determination? And if so, how?
- What role do steroids play in the immune response of both adults and hatchlings?
- How do developing embryos protect themselves from pathogens?
- We conduct much of our research on a marked populations of red-eared slider turtles that inhabit a marsh system adjacent to the Illinois River. Over the past several years we have marked over 1500 turtles making this an ideal system for a variety of studies.
