Vita:

Associate Professor of Anatomy and Vertebrate Paleobiology. .
Ph.D., Integrative Biology, University of California, Berkeley, 1997.
Postdoctoral research, Department of Biomechanical Engineering, Stanford University, 1998-1999.
Postdoctoral research, Department of Ecology and Evolutionary Biology, Brown University, 1999-2000.
Research Associate: American Museum of Natural History, New York (2004-Present); The Field Museum, Chicago (2004-Present).

Research and Professional Interests:

My primary area of interest is evolutionary morphology, with the major focus on the form, function, development, and evolution of the vertebrate musculo-skeletal system. I employ phylogenetic principles and methods from several traditional fields of study (including anatomy, physiology, biomechanical engineering, evolutionary biology, and vertebrate paleontology) to address unique evolutionary questions that are not surmountable within any one discipline. In my current research I am studying:

Means to assess longevity and growth rates in extinct and living reptiles (e.g. dinosaurs, crocodilians) using skeletal growth markers and the use of these data for inferring heterochronic patterns. These data are further used to reconstruct aspects of ancient population biology and ecology.
Crocodilian feeding biomechanics through bite-force experimentation. These tests serve as a springboard for modeling feeding in theropod dinosaurs and fossil crocodilians.
