Zeb Jonker graduated in Medicine (2015) and Neuroscience (2016) at the Erasmus University in the Netherlands. During his master thesis he investigated the role of a common polymorphism in Brain Derived Neurotrophic Factor (BDNF val66met) on cerebellar learning in healthy individuals. Furthermore, he studied the interaction between this BDNF mutation and the effectiveness of cerebellar direct current stimulation (tDCS). He is currently a PhD student in the Rotterdam Neurorehabilitation team (RoNeRes); this is a collaboration between Rijndam Rehabilitation Institute and the department of Rehabilitation medicine of the Erasmus Medical Centre, Rotterdam. His research is focused on motor learning in stroke patients with upper limb disability. The goal is to develop neurophysiological markers for the selection and follow up of personalized therapy.
