We work to understand the neural computations that underlie visual perception by measuring detection and discrimination of carefully specified stimuli.
How are the signals from the three classes of cone photoreceptors processed to give rise to our perceptions of colour? What are the neural circuits of comparison and combination that permit the efficient transmission of visual information from retina to cortex? We specialize in psychophysical experiments with adult observers, but collaborate with physiologists, computer scientists and physicists to inform and constrain our analysis of behavioural data.
International Pupil Colloquium
The Ordered Universe Project
Dedicated to fresh and original examinations of medieval science using interdisciplinary readings of the scientific works of the remarkable English thinker Robert Grosseteste (c.1170-1253), and to present these findings to diverse audiences
The Oxford Vision Group (OxVis) brings together researchers in Oxford who are interested in vision, and provides a forum for the sharing of ideas, skills and approaches.
We hold two meetings a year, with different formats. Our meeting venue alternates between Pembroke College and the John Radcliffe. Here is a list of past events.
OxVis runs with the help of a voluntary committee. Please get in touch if you'd like to help.
