Methodology in causal inference and survival analysis.

Background

I have a master's degree in Industrial Mathematics from NTNU (2015). After completing a Ph.D. in Biostatistics from UIO (2019), I had a research position funded by UIO and the Cancer Registry of Norway (2019-2020) before completing a postdoctoral fellowship at EPFL (2020-2022).
