Présentation

Presentation

My research deals with the evolution of insects. I reconstruct phylogenies before using them as a historical reference to test evolutionary hypotheses. Following this phylogenetic approach, I investigate the evolution of social behavior in termites and cockroaches (Insecta : Dictyoptera), test biogeographic and diversification hypotheses, and study the ecomorphology of cockroaches.

1. Social evolution in cockroaches and termites

In collaboration with E. Bornberg-Bauer (University of Münster, Germany), this project is supported by ANR and DFG. The PhD project of Juliette Berger is instrumental for this project.

2. Ecomorphology and burrowing in granular substrate

The aim of Barbara Bignon’s PhD project is to establish a new dialogue between the physics of granular media (soil, sand, etc.) and behavioral observations of burrowing cockroaches, in order to address fundamental questions about the biology and physics of movement in granular environments for these insects.

3. Factors of diversification in Insects

Combining tip-dating and diversification analyses, Corentin Jouault and Manuel Brazidec (Phd students) want to decipher the factors that have driven the diversification of insects.
