Derek Heim is a Professor of Psychology at Edge Hill University. As a social psychologist with an interest in health behaviours, his primary research areas concern (i) addiction and substance use and (ii) health and well-being. In these contexts, his work focuses on social, cultural and contextual influences which he investigates utilising both quantitative and qualitative research methods.

Derek is also Editor-in-Chief of Addiction Research and Theory the leading outlet for research and theoretical contributions that view addictive behaviour as arising from psychological processes within the individual and the social context in which the behaviour takes place as much as from the biological effects of the psychoactive substance or activity involved.
