Her research focuses on developing Bayesian methods for phylogenetic inference. Professor Heath is particularly interested in methods for integrating fossil and molecular data and understanding macroevolutionary processes from species-level phylogenies. She is working on applying these approaches to biological data sets including penguins, crocodyliforms, turtles, and trilobites. Professor Heath received a PhD from the University of Texas at Austin and was a postdoctoral fellow at the University of Kansas and the University of California, Berkeley.
