 As large scale cohort studies result in complex data structures involving longitudinal observations and time-to-event outcomes and aim at answering causal research questions, most of my methodological research so far has focused on causal inference methods that allow to deal with these data set-ups. In particular, I was involved in developing different methods to estimate direct and indirect effects in settings with a repeatedly measured mediator and a time-to-event outcome. Other ongoing work in the context of mediation analysis focuses on the handling of rare (binary) mediators or outcomes.

A general interest for time-to-event analysis techniques as well as applications in clinical epidemiology has inspired research on the comparison between additive and multiplicative hazard models in practice. Specifically, we are comparing different aspects of Cox's proportional hazards model and Aalen's additive hazard model in context of causal modeling on the one hand, but also predictive and descriptive modelling on the other hand.
