I am a senior fellow in the
Department of Paleobiology at the United States National Museum of
Natural History. I received a B.S. degree in geology from
the University of Wisconsin-Oshkosh, as well as M.S. and Ph.D. in geology from the University of Michigan. My research focuses
on the origin and evolution of cetaceans (whales and dolphins), major
evolutionary transitions in general, functional morphology, use of stratigraphic data in phylogenetic analysis, and theoretical aspects of
diversification. I am currently working on the origins of modern whales
(Neoceti) from archaeocetes and the relationship of these evolutionary
transitions to global climate change at the Eocene/Oligocene boundary.
