My research concentrates on studying red algal diversity and resolving their evolutionary relationships using both morphological/anatomical observations and molecular data. During the course of my postdoctoral project, I have developed several new genetic markers (nuclear and mitochondrial) to improve the phylogenetic resolution of red algae at several taxonomic levels.  I particularly focused on inferring a comprehensive phylogeny of the Florideophyceae, and studying familial and generic relationships within the Rhodymeniales. Recently, I get involved in the “Barcode of Life” project and I am contributing to the development of a DNA barcode database for the red. I joined the algal systematics group at the Muséum National d'Histoire Naturelle in April 2007 where I started to study the biodiversity and phylogeny of the Mediterranean red algae.
