John is a Chartered Psychologist and a Fellow of the British Psychological Society. He is currently a Professor of Psychology at Nottingham Trent University. He was the REF-led for Psychology at Hull University. He had been Professor of Cognitive Psychology at the University of Surrey (1995-2008) and Head of the School of Applied Psychology in Cork (2008-2012) before joining the Department of Psychology in Hull in 2012. He is also an Honorary Professor at Cork and Guildford.
John’s primary research interests are in the measurement of cognitive function; the factors that can protect (sleep, practice, aptitude, genes, pharmaceuticals) or challenge (sleep loss, circadian phase, pain, brain injury, age, inexperience) performance, and the relevance of what we measure under controlled laboratory circumstances to everyday functioning (e.g. activities of daily living, work, driving, etc.). He is increasingly interested in the effects of disease and disability on sleep, and vice versa. Much of his work is necessarily multidisciplinary, and focuses increasingly on the biological and neurological underpinning of cognitive performance.
Over the last three years, John has provided advice/research support for Amazon, Children’s Sleep Charity, Continental, The Family Fund, Manchester United FC, and Vodafone, largely concerning links between sleep and human performance.
