Julien Vitay

Researcher in Computational Neuroscience and Artificial Intelligence

TU Chemnitz

I am researcher and lecturer at the TU Chemnitz, in the lab of Artificial Intelligence of the Faculty of Computer Science.

I was previously postdoc in the Psychology Department of the University of Münster (Germany), under the supervision of Prof. Dr. Fred Hamker and a PhD student at Inria Nancy (France), in the Cortex lab headed by Dr. Frédéric Alexandre.

My research interests focus on computational neuroscience (basal ganglia, hippocampus, dopaminergic system) and neuro-informatics (neuro-simulator ANNarchy). I am also interested in machine learning, especially the recent advances in deep reinforcement learning and its application to robotics.
