Current Research:

Examining the evolution of the archosaur knee joint. I have presented on the condition in extant avialans and crocidiliforms, as well as the condition in hadrosaurid dinosaurs. I am interested documenting when the typical archosaur knee evolved, and where it was modified functionally (e.g. stegosaurs). In the future I would like to examine the developmental genetics of the lateral conyle in birds and archosaurs to establish empirically whether or not they are homologous in extant birds and crocodillians.

Ongoing Interests:

To date most of my research has been related to the biomechanics of extinct dinosaurs. As a result I am particularly interested in developments that will allow the use of phylogenetic inference (e.g. Witmer's Extant Phylogenetic Bracketing system) and the rapidly emerging field of evolutionary developmental genetics (or evo-devo, for short) and the role they can play in understanding how extinct animals worked and changed through time.

I am interested in the origin of birds from predatory dinosaurs. Especially the selective preassures that lead from mainly terrestrial theropods to flying birds, and when, if at all, this process involved an arboreal stage.

I am very interested in evo-devo in general, and especially in the molecular mechanisms which produce novel evolutionary structures.

The adaptationist program is sometimes over-represented in paleontology, but it is in this post Steven J. Gould/spandrel era adaptation is often overlooked in other biological disciplines. It will be extremely interesting to see if techniques can be developed to tease apart true adaptations, exaptations, and structuralist components in living and extinct organisms.
