I am currently...
...a postdoctoral fellow in the Di Santo lab at Stockholm University.➣ Using 3D kinematics, I try to understand why some elasmobranch species choose to walk over swim on certain environmental conditions.
➣ I use µCT scans and specimens from museum collections to characterize long-term mineralization patterns in bony fish facing climate change.
