My activity

My research focuses on the study of genes involved in the skeletal development of the small-spotted catshark (Scyliorhinus canicula). My approach allows candidate gene identification and gene expression localization and quantification, to generate a comparative framework at the vertebrate scale to better describe skeletal evolution. The objective is to understand the origin of biomineralization processes in vertebrates as well as the gene regulatory network used for this. The main techniques I use are: a phylogenetic approach to identify homology relationships of candidate genes between species, quantitative PCR (quantification of candidate gene expression) and in situ hybridization (expression patterns of candidate genes).
In addition to my PhD, I teach organismic biology, developmental biology and zoology to bachelor students.
