St Pauls Visuomotor Group

Welcome to the web pages of the St Paul's Visuomotor Group. Based in the labs of Dr Paul C. Knox in the Institute of Ageing and Chronic Disease’s Department of Eye and Vision Science (University of Liverpool), we also have close links with St Pauls Eye Unit in the Royal Liverpool Hospital (hence the name). We do research in which we investigate vision, the control of eye movement and visually guided behaviour in health, ageing and disease. Details of ongoing projects and publications can be found on the relevant pages.
