Research Description

In the Davis Lab, my students and I investigate how evolution and development interact to generate the diversity of organismal forms we see in the world.  More specifically, we study the gene regulatory networks that drive the development of vertebrate appendages (fins & limbs).  We take a broadly comparative approach, studying vertebrates such as paddlefish, sharks, zebrafish, and salamanders to test our hypotheses.  The insights gained from our research have the potential to inform congenital birth defects research and regenerative medicine.
