General research interests center on vertebrate evolution, with specific emphasis
on development in amphibians and reptiles. My research approach is a comparative
and integrative, typically focused on aspects of skeletal development as a tool to
compare evolution across different life history strategies. Recent investigations
have focused on the impact of calcium resource provisioning during development in
the evolution of viviparity in reptiles. I also have interests in exploring the role
of honors, undergraduate research, and internship experiences in enhancing undergraduate
