Former Lab Members

Dr. Séverine Toussaint. Alexander v. Humboldt postdoctoral fellow. Her postdoctoral research project aims at better understanding the acquisition of nails and grasping mechanisms in early primates. now here

Dr. Fabio Alfieri. His project aims to characterize the convergent evolution of humeral and femoral functional anatomy in mammals adapted to the slow arboreal lifestyle, in a phylogenetic framework.

Dr. Eli Amson. Alexander v. Humboldt postdoctoral fellow. We continue to collaborate on various projects.

Kathrin M. Amelung. M.A. She went on to the Bauhaus University of Weimar, Germany where she is continuing her work on her PhD project which focusses on the term „illustration“.

Dr. Patricia Berles studied the jumping behavior and correlated differences in hindlimb morphology of the Callitrichidae (Mammalia, Primates). finished 2026 „On adaptation: an integrative study of leaping behaviour and functional morphology of the hind limb in callitrichid primates as model systems“
