He specialises in causal analysis of observational data, and is particularly interested in within-case comparisons, matched cohort designs, and simulation-based approaches to create intuitive effect estimates. He is a member of the NIHR Public Health Research funding committee. Dan is a Consultant in Public Health and can supervise public health trainees who are interested in health research.
