Since 2012, Ian has been an investigator on research attracting over £11.5 million of funding. He is the intervention modelling work package lead on a NIHR programme grant to improve the use of prescribed medicines at transitions, and intervention development and testing workstream lead on a NIHR programme grant to develop and evaluate a diabetes self-management intervention for people with severe mental illness. His research has been funded by Cancer Research UK, Canadian Institutes of Health Research, ESRC, Health Foundation, HS & DR, HTA, MRC (PHIND, JGHT, Trial), NHS England SBRI, NIHR, and the (ESRC) White Rose Consortium.

Ian attained chartered status as a health psychologist in 2006.

He served on the UKSBM executive committee in the role of publicity officer from 2007-2011, on behalf of whom he submitted evidence to the House of Lords Science and Technology committee on behaviour change. He rejoined UKSBM exec committee in 2018, in the role of Social Media Officer. He served as lead of the Behaviour Change Grand Challenge within the School of Psychology from 2013-2016.

Ian has supervised 5 PhD students to completion, all of whom remain active within academia. He currently supervises 2 PhD students within the School of Psychology, and co-supervises 2 PhD students and 1 NIHR pre-doctoral fellow elsewhere within the University of Leeds, 1 MPhil student elsewhere within the UK, and is a dissertation committee member for 1 PhD student in the USA and 1 elsewhere in the UK.

Background

After graduating with a BA in Social Psychology from the University of Sussex, Ian undertook a D.Phil. entitled “Evaluating Brief Theory-Based Interventions to Promote Health Behaviours”, supervised by Professor Charles Abraham, and funded by an ESRC studentship award. Ian then accepted a post as Research Fellow at the Centre for Health Care Research at the University of Brighton, co-authoring a scoping exercise for the National Co-ordinating Centre for NHS Service Delivery and Organisation R&D, entitled “Concordance, Adherence and Compliance in Medicine Taking” with Professor Rob Horne. Ian subsequently joined the Primary Care Unit at the University of Cambridge, lead by Professor Ann-Louise Kinmonth, in the role of research psychologist, developing behaviour change interventions on a series of randomised controlled trials related to medication adherence, diabetes screening, and self-monitoring & physical activity.

Research interests

I'm interested in helping people do what they say they want to do This is typically in the context of developing and evaluating interventions to promote health behaviour change. I employ evidence synthesis techniques and qualitative and quantitative approaches in the development of behaviour change interventions and test their acceptability, deliverability, and efficacy in feasibility and phase 2 randomised controlled trials. I have an interest in employing mHealth apps, mobile sensing, wearables and objective measurement in their evaluation.
