I am a vertebrate paleontologist specializing in the functional anatomy of the appendicular skeleton in mammals. I am broadly interested in how patterns in mammalian morphology and diversity reflect changing climates during the Eocene epoch (55–34 million years ago), a period of time in which most modern mammal groups evolve. In particular, my research focuses on two main areas:
- How locomotion is reflected in the morphology of the appendicular skeleton and how the evolution of locomotion reflects changes in climate
- How changes in taxonomic diversity (i.e. how many different types of mammals exist at a particular time period) reflect changes in local habitat and climate
As a part of my research program, I perform museum, laboratory, and field based research. I have several potential opportunities for student involvement, including building models of fossil material from microCT scans, and preparation and identification of fossil specimens. Students interested in pursuing research in my lab are encouraged to email me for more information.
