Short Biography

Professor Marius Usher has received his PhD in Physics at Tel-Aviv University with a dissertation on neural-network modeling. Following this he pursued postdoctoral training in visual psychophysics (Weizmann Institute), in computational-neuroscience (Caltech) and cognitive psychology (Carnegie Mellon University). In 1995 he started to lecture in Psychology in England (University of Kent and Birkbeck College, London). From 2004 he was a Professor of Cognitive Psychology at Birkbeck College, University of London. In 2008 he returned and started to teach at Tel-Aviv University .
