Main research question
I am interested in the role played by food material properties and ingesting behavior in the evolution of dental form and function, especially in primates.
Topics of study
I am currently collaborating with Drs. Franck Guy and Vincent Lazzari for the DietPrime ANR:
- Anatomy: Identification of primate dental tools by combining the study of their dietary behavior and of the topography of their dental crowns;
- Biomechanics: Study of the material properties of the plants consumed by extant primates, using a portable universal mechanical tester (FLS-2);
- Programming: Development of doolkit, an R package allowing to explore, measure and compare 3d dental topography.
I am also working with Gildas Merceron and the consortium of the DietScratches ANR:
- Anatomy: Study of the dental topography of domestic pigs from the project;
- Biomechanics: Study of the material properties of the food eaten by the project’s pigs;
- Programming: Development of trident, an R package for measuring and comparing dental microwear textures.
Fieldworks
I studied fossil primates from the Miocene of the Balkans. I am also interested in extant primates living in their natural environment.
