Dr Jan Lauritzen

Dr Jan Lauritzen graduated in neuroscience from St. Catharine's College Cambridge in 1997, followed by an MPhil on computational modelling of contrast processing in the mammalian visual cortex.

Jan completed the research for his PhD (Contrast Normalisation and the Visual Coding of Contrasts in Natural Images) in 2001 in the Department of Physiology at Cambridge.

He worked as a Lecturer in Vision Science in the School of Biomedical Sciences at the University of Ulster from 2001-2008, and is currently a Senior Lecturer in Physiology in the School of Life Sciences at Kingston University.

Jan's research focuses on human psychophysics of early visual processes in the retina, primary visual cortex and extrastriate areas, and computer modelling of those processes. In collaborations, Jan also has a wider multidisciplinary interest in computer modelling of physiological and biological processes in general, and the design of psychophysical protocols for sensory physiology and clinical evaluation of human vision.
