I have a Master degree in marine ecology and I am currently doing my PhD in evo-devo on cartilaginous fishes, especially on catsharks (scyliorhinids). I try to describe their tooth shape diversity using microCT scans, 3D geometric morphometrics, and machine learning. Then, I am deciphering what drives such diversity, including physical and molecular parameters. I work under the co-supervision of Nicolas Goudemand and Mélanie Debiais-Thibaud. I also work on the axial regionalisation of the vertebral column of skates, on the evolutionary history of mineralising cells in chondrichthyans, and on chimaera husbandry in aquaria. I participated to the organization of the Comparative Cartilage Biology meeting.
Exploring tooth shape diversity in sharks
We quantify shark interspecific tooth shape patterns and seek for physical contraints to explain this diversity.
Intraspecific tooth shape variation
I characterize the intraspecific tooth shape variation -mostly in scyliorhinids- among sexes and across growth stages.
Mineralizing cells in chondrichthyans
Comparing mineralizing cell types of the endoskeleton of sharks, skates, rays, and chimaeras.
I describe the axial regionalisation of the vertebral column in the thorny skate Amblyraja radiata.
Tooth & odontode development
Comparing gene expression patterns between teeth and odontodes.
Two populations: same teeth?
Discriminating teeth from distinct shark populations.
Growing chimaeras in aquaria
Optimal parameters and life history traits.
