Pierre Vassiliadis

MD, PhD Student

Pierre is a MD who did his PhD jointly between the CoActions Lab and the Hummel Lab at the Ecole Polytechnique Fédérale de Lausanne (EPFL). Before that, he joined the CoActions lab in 2014 as a research student during his medical studies at UCLouvain. During his time in the lab, Pierre worked on the development of a new double-coil TMS approach allowing to obtain motor-evoked potentials in both hands simultaneously (Vassiliadis et al., 2018, Front Neurosci, Vassiliadis et al., 2020, JNP) and on the effect of reward on motor learning (Vassiliadis and Derosiere, 2020 JNeurosci, Vassiliadis et al., 2021, iScience, Vassiliadis et al., 2022, iScience). Pierre is now a post-doctoral fellow at EPFL where he works on the development of transcranial Temporal Interference Stimulation (tTIS), a new, non-invasive approach to target deep brain regions non-invasively (Wessel, Beanato et al., 2023, Nat Neurosci, Vassiliadis et al., 2023, biorxiv).
