  • BA in Biological Sciences, University of Chicago


My courses showcase the amazing diversity of life's forms, focusing particularly on how this diversity evolved over time and on the links between form, function, and environmental demands.


I am a functional morphologist and evolutionary biologist broadly interested in how animals work and how organismal diversity evolves. My research focuses on identifying general patterns in the diversification of vertebrate form and understanding the evolutionary processes that give rise to them.
