I am interested in evaluation methods and the application of systems thinking and complexity science to public health evaluation. I led on the development of a complex systems approach to process evaluation (https://doi.org/10.1371/journal.pmed.1003368) and was the lead researcher on the NIHR SPHR Systems Evaluation Guidance for local practioners.

I have a particular interest in the commercial determinants of health and have conducted systems-level process evaluations of local alcohol interventions.

I am also interested in the broader social determinants of health and much of my recent research has focussed on how strategies, policies and interventions are designed to influence place-based determinants of health in local environments.

My previous research was conducted with a programme of work entitled 'Evidence Beyond the Health Sector' that looked into attitudes to, and views and understandings of, research and evidence among practitioners and policy-makers in policy fields relevant to the urban built environment.

I have extensive systematic review experience and contributed to a series of reviews to inform the development of NICE Public Health guidance on tuberculosis.
