Generally interested in the evolution of unicellular eukaryotes, Loïc currently works at the Station Biologique de Roscoff. During his post-doc, he tries to understand the molecular mechanisms that regulate symbiotic associations between collodarian Radiolaria and their specific microalgal symbionts. Using a phylogenetic approach, he also tries to clarify the evolutionary history of Nassellaria, which represent important index fossils, widely used in biostratigraphic studies and paleoenvironmental analyses.
