Visiting Professor
at the Charité

Event series by Prof. Dr. med. Peter Vajkoczy and Aesculap

The event series “Visiting Professor at the Charité” aims to attract established specialists and leading figures in neurosurgery to expand the neurosurgical horizon of mainly junior clinicians and academics through lectures and hands-on workshops held at the Charité. At the same time, the interested public is invited to attend open lectures organized for the event.

The main objective, knowledge transfer from renowned neurosurgeons to eager young colleagues, reflects the corporate philosophy of Aesculap, the exclusive cooperation partner of this event series: “Sharing Expertise”.
