My research activities are based on two main themes:

1- The study of local adaptation in plants tolerant to heavy metals, including  Thlaspi caerulescens (Noccaea caerulescens) as a biological model.

This theme is developed in the laboratory with Ophélie Ronce and Agnès Mignot. The tools used in these studies are primarily demographic, population genetics and reproductive system studies.
