Research Interest:

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 education.
