I am an associate professor of health psychology with expertise in developing and evaluating interventions that use behaviour change techniques for implementation both in the UK and in LMICs. I have been an investigator on research grants totalling £27.5 million of funding, of which 16 were peer-reviewed Research Council grants, including 5 NIHR Programme Grants for Applied Research and 2 NIHR Research and Innovation for Global Health Transformation grants.
I am currently a co-investigator on 12 funded studies, of which 3 include trials in ODA-recipient countries. These funded studies include intervention development / evaluation for support for people with TB & co-morbid depression, improving communication for people with aphasia, physiotherapy rehabilitation, medication adherence, medicines optimisation, self-management of long-term conditions for people with severe mental illness, tobacco cessation/harm reduction, and tooth brushing.
Among other responsibilities, I am the intervention modelling work package lead on a NIHR programme grant to improve the use of prescribed medicines at transitions, intervention development and testing workstream lead on an NIHR programme grant to develop and evaluate a diabetes self-management intervention for people with severe mental illness, and intervention adaptation workstream lead on an NIHR programme grant to develop and evaluate a behavioural activation intervention for people with co-morbid depression and diabetes in South Asia.
My research has been funded by Cancer Research UK, ESRC, Health Foundation, MRC (PHIND, Trial), NHS England SBRI, NIHR (HS&DR, HTA, PDG, PGfAR, RIGHT), Nuffield Foundation, Wellcome Trust, and the White Rose Consortium. Current projects include:
- The APT project
- CLASS III
I attained CPsychol (Health) in 2006. I am a member of the College of Experts to support the DHSC/UKRI Global Effect on COVID-19 Health Research. Between 2018 and 2020, I chaired the advisory group for an NIHR-funded evidence synthesis project looking at multiple risk behaviour interventions for people with severe mental illness. I 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.
I rejoined the UKSBM exec committee in 2018-2021 in the role of Social Media Officer. I served as lead of the Behaviour Change Grand Challenge within the School of Psychology from 2013-2016. I was a principal collaborator on the NIHR CLAHRC-YH Evidence-Based Transformation theme and a match-funded collaborator on the NIHR CLAHRC-YH Mental Health and Co-Morbidities theme. I was an NIHR CLAHRC Yorkshire & Humber Fellow (2014 - 2015). I have served on the editorial board of the British Journal of Health Psychology since 2006, the Journal of Patient Preference and Adherence since 2015, and as an academic editor for PLOS ONE from 2015-2019.
I have supervised 9 PhD students to completion. I currently supervise 2 PhD students and 1 NIHR clinical doctoral fellow elsewhere within the University of Leeds, and am a dissertation committee member for 1 PhD student in the USA and 1 elsewhere in the UK.
