My activity

My PhD focuses on the links between life history traits and speciation. I am studying this question using a comparative genomic analysis of 20 species of marine fish with contrasting life history traits (sardine, seahorse, hake,…) subdivided into two genetic lineages in the Atlantic and Mediterranean representing different stages on the “speciation continuum”. By reconstructing the demographic evolutionary history, the inference of divergence times and of introgression into the genome for each of the species pairs, the goal of my thesis is to identify the life history traits impacting the speed and the establishment of barriers to gene flow during speciation.
