Dr Stuart Wallis

Stuart graduated with a BSc (Hons) in Psychology in 1987 at Birmingham University. He then spent several years in the Civil Service, working for the Lord Chancellor's Department. Desiring a change of career, he completed a 2nd undergraduate degree, and graduated with a first class BSc (Hons) in Optometry at Aston University in 2005. He then completed a PhD in Vision Science under the supervision of Professor Mark Georgeson, at Aston University. His thesis was submitted in 2009 and was on 'Low level feature detection in human vision'. He was then employed as the named post-doctoral researcher on BBSRC grant number BBH00159X1, working on binocular fusion and diplopia in human vision. Stuart then worked as a Sessional Lecturer, teaching Research Methods and Statistics, and Auditory Perception, followed by a year as a Research Fellow on the ARCHA ExtraCare project and two years on a project that aimed to improve the reading ability of a cohort of Macular Degeneration patients. Currently employed as a Research fellow in the Aston Laboratory for Immersive Virtaul Environments (ALIVE).
