Main research question

I explore the feeding ecology of extant and extinct ungulates, the influence of environmental factors on this ecology and the contribution of ungulates feeding behavior as a (paleo)environmental bioindicator.

Topics of study

Dental Microwear Texture Analyses (DMTA) constitue my main approach.

One of my research focuses is a better paleoenvironmental regional characterization for early Pleistocene European localities, period that coincides with Homo dispersion in Europe.

In New Caledonia I study the destructive impact of extant deer populations on natural habitats. DMTA is proposed as a managing tool. I built a reference database unparalleled in the world.

For Middle Paleolithic and Tardiglacial I explore variations in deer feeding behaviors in order to make the link between cultural changes in human societies and climatic oscillations.


New-Calédonia is my main field of investigation. Its insular and therefore constrained context constitutes a perfect model to address archeological and paleontological questionings.
