Fidji Berio
Scyliorhinus head



I am a postdoctoral fellow in the Di Santo lab at Stockholm University. I work on the kinematics of walking elasmobranchs and the mineralization patterns in bony fish facing climate change.

Background
I completed a Master's in marine ecology at the European Institute for Marine Studies. I did my thesis on the axial regionalisation of the vertebral column of skates at the Université du Québec à Rimouski, Canada.
I did a PhD in evo-devo on cartilaginous fishes, especially catsharks (scyliorhinids), at the Institute of Evolutionary Sciences of Montpellier. I described their tooth shape diversity using micro CT scans, 3D geometric morphometrics, and machine learning. I aimed at deciphering what drives such diversity, including physical and molecular parameters.
I also worked on the evolutionary history of mineralising tissues in chondrichthyans and chimaera husbandry in aquaria in partnership with the aquarium Planet Ocean Montpellier.
