Professor Roger Hugh Stephen Carpenter (born 2 September 1945) is an English neurophysiologist, Professor of Oculomotor Physiology at the University of Cambridge.

Early life

Carpenter was educated at Gresham's School, Holt, Norfolk, where he was a member of Farfield (1958–1963),[1] and then at Cambridge.

Career

Before being appointed as Professor of Oculomotor Physiology in the University of Cambridge, Carpenter was a Director of Studies in Medicine at Caius College. In his principal field, mechanisms of consciousness, his position can be described as a one-way Cartesian. He is the creator of EPIC (the Experimental Physiology Instrumentation Computer) and NeuroLab, a set of interactive demonstrations on the working of the human brain.[2][3][4]

In his spare time, he runs the CUDOS project (Cambridge University Distributed Opportunity Systems), aimed at using medical students' gap year between school and university. He was previously Director of a group called the Susato Consort and Susato Baroque Ensemble.[2][5]

In 2000, Carpenter was one of a group of twenty inaugural winners of a National Teaching Award of £50,000 from the Institute for Learning and Teaching in Higher Education.[6]

Interests

Carpenter's work focusses on mechanisms of decision. Measurement of saccadic latency, the time taken to choose a visual target and initiate an eye movement, is a reliable method for obtaining reaction time data. This work has inspired a model referred to as LATER (Linear Approach to Threshold with Ergodic Rate) to explain the decision mechanism. Technological advances enable oculomotor measurements to be made both quickly and non-invasively, using micro-devices which have many clinical applications.[7] He also has professional interests in vision in general, motor systems, and physiological mechanisms of consciousness.[2]

On a Cambridge web site, Carpenter describes himself as "Philosopher, mad scientist, and artiste extraordinaire".[2]
