Dr Hartwig's research interests are related to the field of causal inference in epidemiology, with emphasis on empirical and methodological work on instrumental variable analysis. He is also interested in translation of statistical methods between different fields of epidemiology. He is returning to Bristol to continue the work undertaken with Professor George Davey Smith in the Medical School in 2022. They are working on the project Empirically assessing the plausibility of unconfoundedness in observational studies.
