My main research interests are causal inference and time-to-event analysis. In particular, I am interested in methods for studying time-varying treatments, time-dependent confounding and other sources of bias in longitudinal settings, time-to-event outcomes, competing risk problems and more general multi-state modelling. I also have an interest in infectious diseases, including the added complexities of estimating treatment effects in such settings, estimation of excess mortality and infectious disease surveillance and modelling.
I am interested in applications using data from both randomised and observational studies, and in particular event history data constructed from linked clinical and population-wide registries. I am currently involved in various collaborative projects, e.g. on the effects of rehabilitation and pain medication on patient outcomes after traumatic injury with researchers at the Oslo University Hospital, and on the effects of rehabilitation and workplace initiatives on long-term sick leave and work-related outcomes with researchers at the National Institute of Occupational Health in Norway, with funding from the Research Council of Norway and the Institute of Basic Medical Sciences, University of Oslo. At the Norwegian Institute of Public Health I’m involved in projects on the estimation of vaccine effects.
