Research

My research focuses on the eco-evolutionary dynamics of species interactions. I am interested in various empirical systems, such as animal gut microbiota or plant mycorrhizal symbioses. To explore the ecology and evolution of these interactions from different angles, I combine field studies, environmental genomics and the development of statistical approaches and mathematical models.

Teaching

I teach botany and plant ecology at bachelor and master's level at the Université Toulouse III - Paul Sabatier.
