I am Associate Professor (Docent) of Practical Philosophy at Stockholm University, Pro Futura Scientia Fellow at the Swedish Collegium for Advanced Study, and Researcher and Advisor at the Institute for Futures Studies. I am also associate editor at the British Journal for the Philosophy of Science, where I handle papers on decision theory and probability theory.

My current research mostly concerns how one should choose in situations of extreme uncertainty, including situations where one suspects that the outcome of one’s actions (or inaction) could be catastrophic.

I defended my PhD thesis from the London School of Economics and Political Science in 2014.
