Pierre Vassiliadis

MD, PhD Student

STR 4393Pierre is a MD who specializes in Neurology. He joined the CoActions Lab in 2014 as a research student during his medical studies at Université Catholique de Louvain. During his master thesis, he has worked on two main projects including (1) the investigation of the involvement of the motor cortex in reward-based decision making and (2) the development of a new double-coil TMS method allowing to obtain motor-evoked potentials in both hands simultaneously (cfr Innovation section). Pierre is now performing a joint PhD between UCLouvain (supervisor: Prof. Julie Duqué; co-supervisor: Dr. Gerard Derosiere) and the Ecole Polytechnique Fédérale de Lausanne (supervisor: Prof. Friedhelm Hummel) investigating the impact of sensory and reward feedback on motor learning
