- Profile
-
I am a professor of Health Psychology with expertise in co-producing and evaluating interventions that use behaviour change techniques and implementation strategies both in the UK and in LMICs. I have been an investigator on research grants totalling £28.5 million of funding, of which 17 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 10 funded studies, of which 3 include trials in ODA-recipient countries. I have led or co-led 10 workpackages where I have employed behaviour change and/or implementation science theory to structure knowledge mobilisation across evidence synthesis, qualitative interviews, co-production of intervention and/or implementation and process evaluation, including the intervention adaptation work package for a behavioural activation intervention for the treatment of depression in people with diabetes in Bangladesh and Pakistan; the evidence synthesis work package and the implementation modelling work package for an intervention programme for depression and TB in Pakistan and Afghanistan; the intervention development work package for an intervention to support diabetes self-management for people with severe mental illness; the co-design work package and the intervention optimisation work package for a digital intervention to support painful distal upper limb musculoskeletal disorders; and the theory of change work package and mixed-methods process evaluation work package for anti-psychotic switching intervention targeting guidelines implementation among mental health professionals.
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.
