Topics: paleoanthropology, taphonomy, zooarchaeology
The goal of my scientific career is to contribute to paleoanthropology by supplying new data and analyses in three areas of the science:
1) developing, standardizing, and utilizing better methodology for recording and analyzing fossil and modern human morphological variation and zooarchaeological data;
2) engaging in rigorous field work, using detailed and advanced methods to find more fossil specimens and archaeological sites, in order to fill in the main gaps in the hominid record;
3) with the information gained from areas 1 & 2, testing hypotheses about the evolution, ecology, and behavior of fossil hominids.
Over the last three years, my research program has expanded to include taphonomic and zooarchaeological studies of Middle and Late Pleistocene sites in France and Plio-Pleistocene sites in Africa, in order to test hypotheses about the evolution, ecology, and behavior of fossil hominins. I have had the opportunity to learn from Dr. Richard Klein and apply the methods he has developed over several decades to the fossil fauna from Orgnac 3, a Middle Pleistocene site that has provided important yet little-studied hominin remains and abundant lithic and faunal material. My dissertation research has focused on building a taphonomic and paleoecological framework with which to analyze the fossil fauna in order to reconstruct hominin subsistence behavior during the “Muddle in the Middle”. I am working with Drs. Ludovic Slimak (CNRS), Christian Tryon (NYU) and others on a Leakey Foundation-funded project to revise and refine the chronology of the Orgnac 3 site using new methods such as micro-tephra fingerprinting and K/Ar dating. Co-director Ludovic Slimak and I are planning future excavations at Orgnac 3, in addition to our current work at the Late Pleistocene site of Le Grand Abri aux Puces, and at the Late Mousterian/Pre-Aurignacian site of l’Abri Rothchild (please see personal website for details and links to publications), for which I am the paleoanthropologist/zooarchaeologist. Starting summer 2011, I have been integrated into the West Turkana Archaeological Project in Kenya (previously led by Dr. Hélène Roche, next year to be lead by Dr. Sonia Harmand) as paleontologist/zooarchaeologist (along with Jean-Phillipe Brugal) and paleoanthropologist (with Dr. Sandrine Prat).
