Research and Activities:

My research has focused on applying computational phylogenetic methods to the hominin fossil record.  Specifically, I am interested in exploring the potential for interspecific hybridization between hominin species by employing novel analytic methods borrowed from evolutionary biology and bioinformatics.  Additionally, I am interested in how these methods may useful in understanding relationships between closely related extant primates.

I am also interested in paleoecology, paleodemography and climate change during the late Pleistocene, and recently finished a project involving Pleistocene population density and LGM habitable land area calculations in the Old World.  I am currently using similar methods to study habitable land area and population demography during periods of climatic extreme in the New World.
