My research activities explore how mammals responded in the past to long-term changes in environment, available resources and competition. I specifically focus on the reconstruction of dietary behaviors through dental microwear analysis, the study of the abrasions left by food on the dental enamel surface.

My current research focuses this technique. I’m working on developing dietary reconstruction models using 3D dental microwear analysis on a dataset resulting from controlled-food testing on domestic sheep (ANR TRIDENT, principal investigator: Gildas Merceron). This work will help us characterize how microwear is formed, and further our understanding of the feeding behavior of extant and fossil herbivores.
