Présentation

Thèmes de recherche

Mon cadre général de recherche s’inscrit dans la variation phénotypique. Plus précisément, j’étudie les liens qui existent entre la forme et la fonction, le résultat de cette association étant la cible de la Sélection Naturelle. Ma méthodologie de prédilection est la morphométrie (classique, géométrique 2D et 3D). Les vertébrés et les îles offrent des patrons morpho-fonctionels particulièrement intéressants, au cœur de mes recherches. Mes études portent sur la faune actuelle, archéologique et paléontologique.

Research interests

My general research framework concerns phenotypic variation. More precisely, I study relationships between form and function, this association being the principal target of natural selection. My methods of choice is morphometrics (traditional, geometric, in 2D and 3D). Vertebrates in an insular context present very interesting morpho-functional patterns that occupy the main part of my work. These approaches are also applied on archaeological and palaeontological specimens providing a better understanding of topics such as domestication and phenotypic evolution. My knowledge and my experience in morphometrics has resulted in numerous collaborations, for example with UMR 7209 : « Archéozoologie, archéobotanique », UMR 7179 : « Mécanismes Adaptatifs : des Organismes aux Communautés » and the UMR 7207 : « Centre de recherche sur la paléobiodiversité et les paléoenvironnements ».
