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 and 3D geometric morphometrics. 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 am also involved in side projects about the skeletal patterns in skates (University of Québec in Rimouski in the Paléobio lab), about the evolutionary history of mineralizing cells in Chondrichthyans, and 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 endoskeleton of the thorny skate Amblyraja radiata and particularly the vertebral column.
Tooth & odontode development
Comparing gene expression patterns between teeth and odontodes.
Two populations: same teeth?
Discriminating teeth from distinct shark populations.
