About

Overview

David Crabb is Professor of Statistics and Vision Research and he joined City University London in 2005. David gained degrees in Mathematics and Statistics at Oxford and Sheffield before completing a PhD in Visual Science in 1996. Following a post-doctoral position at University College London and a lectureship in Nottingham, he took up his position at City University London in 2005.

Research

Research Overview

David's research laboratory contains a lively mixture of vision scientists, ophthalmologists, psychologists, mathematicians and computer scientists. This research laboratory focuses on measurement in vision: visual fields, imaging, visual function and quality of life, and medical statistics. One of the main themes of his work in glaucoma is relating the different stages in the disease process to patient's visual disability.
