Research Interests
The phylogeny and evolutionary history of the euryapsids, primarily marine reptiles of the Mesozoic Era, including ichthyosaurs, placodonts, and sauropterygians, the empirical testing of cladistic methods of phylogeny reconstruction using digitally simulated phylogenies, and the incorporation of data from CT scans of fossil specimens in the morphological description of fossil taxa.
