Research interests include food policy, commercial determinants of health (focused on food industry, but also as compared to other industries), policy evaluation, qualitative research, including qualitative systems methods. My programme of research comprises evaluations of public private partnerships and food industry led self-regulation, as well as analyses of the process, and impact, of the growing influence of large food corporations in health, in England and abroad. This falls into my broader programme of work driven by our Commercial Determinants Research Group (CDRG), and included under the UKPRP funded SPECTRUM consortium on the commercial determinants of health. I currently lead the public health policy arm of the LSHTM Policy Innovation and Evaluation Research Unit (PIRU), including a 3-year project on food provision in early years (childcare) settings in England. I also lead the LSHTM team of the CO-CREATE project, an European Commission-funded project on systems thinking to address adolescent obesity. I lead a 2023-25 Gates-funded project (via the IMMANA programme) on the use of qualitative systems methods to examine food industry involvement in emergency food assistance in Lebanon. I supervise several doctoral students.
