John Groeger

Professor

School of Social Sciences

Role

John’s role primarily involves research, and research leadership, as well as management responsibility for research support and funding within Psychology. John is also an active teacher (contributing to Research in Context (PSYC10159), Individual Differences and Conceptual and Historical Issues in Psychology (PSYC20215)) and supervisor of undergraduate and postgraduate research.

Career overview

John is a Chartered Psychologist and a Fellow of the British Psychological Society. He was appointed Professor of Psychology at Nottingham Trent University in June 2017.

He has been REF-lead for Psychology at a number of institutions, is a former honorary General Secretary of the British Psychological Society, and President of the Traffic & Transport division of the International Association of Applied Psychology.

John has held chairs in Psychology at the University of Surrey (1995-2008), University College Cork, (2008-12, also Head of School) and the University of Hull (2012-2017). In addition, he is/has been Honorary Professor at Cork and Surrey.

Before these professorial appointments, John was a member of the Medical Research Council’s Applied Psychology Unit in Cambridge from the mid-80s to mid-90s, where he went to following his PhD at Queen’s University Belfast (1984), and obtaining a BA (1979) and MA (1981) from UCC, in his native Cork.

He is the author of two books, one on memory, one on driving; founding editor of Elsevier’s Transportation Research: Traffic Psychology and Behaviour; and author of 80+, peer-reviewed publications, and over 200 book chapters, reports, etc.

Research areas

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, shift working and operator safety in complex settings. Much of his work is necessarily multidisciplinary, and focuses increasingly on the biological and neurological underpinning of cognitive performance.

External activity

John enjoys presenting his and others’ research at public science events, as well as scientific conferences.

Sponsors and collaborators

Over the last three years, John has provided advice/research support for Amazon, Ava Ltd., Children’s Sleep Charity, Continental AG, The Family Fund, Manchester United FC, and Vodafone, largely concerning links between sleep and human performance.
