Current Research Interests
My basic interest is in unraveling the evolutionary history of humans and our close relatives. The inherently interdisciplinary nature of paleoanthropology has led me to study human fossils and their archeological record and the interrelationships of living and extinct Old World monkeys and apes (and to a lesser degree that of other primates). I have used the patterns of Old World monkey evolution to clarify the chronological framework for human evolution in Africa and also to approach general questions of evolutionary processes and patterns. Current projects include the description and analysis of fossil monkeys from Africa, Europe, India and China, as well as the clarification of systematic relationships among all Catarrhini. A continuing interest is the integration of human paleontological, archeological and paleoenvironmental evidence bearing on the evolutionary history of humans. My goal is the synthesis and integration of diverse data, which has drawn me into a variety of editorial ventures.
Along with a group of colleagues and grad students (the NYCEP Morphometrics Group), I am working on several projects in the broad field of geometric morphometric analysis and 3D morphology. Our major current project is to reconstruct the shape of the cranium at various points along the evolutionary tree of Old World monkeys, combining digitizer and laser-scan data on modern and fossil skulls in a framework of statistical analysis and computer-graphic visualization.
My latest venture is a collaboration with French colleagues Claude Guérin and Martine Faure (Lyon) to re-study the late Pliocene (2 million year old) fossil mammal site of Senèze, located inside an extinct volcano in the Massif Central. we are seeking to collect new fossil specimens of rare species belonging to a well-known fauna, obtain more precise estimates of the fauna’s age and to better understand how the site was formed and what the environment was like at the time the mammals lived there.
