Our lab employs evolutionary and developmental approaches to ask: how does morphological novelty evolve, and what are the causes of major evolutionary transitions?

This research focuses on vertebrate appendages—fins and limbs—which are powerful models for testing hypotheses of developmental evolution and the relationship between form and function.

We are at located at 218 Mueller Laboratory at Penn State University in the Department of Biology.
