A fully funded 3-years PhD position (EU MSCA-COFUND program) is available at Aix-Marseille University (France) for motivated students interested in the behavioral, neurophysiological and computational investigation of multistable visual perception in healthy and pathological populations. The project is strongly cross-disciplinary, including psychophysical and oculomotor experiments as well as advanced computational modeling. It will also involve an international mobility at the University of Edinburgh (UK), as well as a collaboration with the psychiatry department of Lille Hospital (France).
