I am one of the leading health economists in the UK with around 200 publications (h-index 58), and a world-wide reputation for methodological and applied research. My areas of expertise include extending causal inference methods to generate Real World Evidence (RWE) in ways that improve decision-making. I also have related applied interests around new technologies and care pathways in cancer, evaluations of alternative forms of surgery, and method developments around new study designs, including adaptive trials.

    
I lead a research team of health economists and statisticians undertaking health economic research of global interest. Over the last ten years I have generated total research grant income of around £80 million, and have led major studies of international relevance to successful completion and impact on policy.

I currently lead two major NIHR funded projects, SORT (Surgery or Radiotherapy for Early Stage Cancer) and TACTIC (Timeliness of access to Cancer Treatment- Improving Care). I am on the NIHR funding panels for Programme Grants for Applied Research and Ressearch Professors. I am an Associate Editor for a major health economics journal, Health Economics. I have delivered keynote (invited) talks to multidisciplinary audiences in the US, Canada, China, Taiwan and in the UK, and written editorials for leading clinical and health economics journals. I provide scientific advice to the UK Department of Health and to NICE. I served on the 2021 REF subpanel 2, Public Health, Health services and primary care.
