I joined Hull in September 2012, having been Head of the School of Applied Psychology in my native Cork (2008-2012), and Professor of Cognitive Psychology at the University of Surrey (1995-2008). I feel honoured that each of these institutions have awarded me Honorary Professorships, and I continue to collaborate with academic in both Cork and Guildford.

Since joining Hull I have established the Departments Marketing Committee, and have, since January 2014, been Director of Research, as well as chairing the Department's Research Committee.

I am a Chartered Psychologist, and a Fellow of the British Psychological Society.


I teach at all levels of our degree programmes, but my main involvements are with Learning & Cognition (Year 2), where I lecture on Thinking and Consciousness, and my final year optional course on the Psychology of Sleep.


Research Interests

My 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). I am increasingly interested in the effects of disease and disability on sleep, and vice versa. Much of my work is necessarily multidisciplinary, and focuses increasingly on the biological and neurological underpinning of cognitive performance.
