I am a paleontologist with a focus on documenting and interpreting the diversity in organismal body forms through time. In particular, I am interested in examining the dynamics during major evolutionary transitions, such as the initial diversification of individual phyla as well as all metazoans along with exploring the methods used to illuminate these patterns. My research is often focused on patterns within echinoderms (particularly crinoids) exploring their paleobiology, systematics, morphology, taphonomy and early evolutionary history.
