Starting in 2026, I will be a Pro Futura Scientia Fellow and researcher at Stockholm University’s philosophy department.

At the moment, I am a researcher at the Institute for Futures Studies where I am the PI of the VR-funded project Expertise in crises (2023-25), which studies the role of experts in high uncertainty, high stakes situations like the Covid-19 pandemic. 

My work spans decision theory, social epistemology, and philosophy of science. I tend to work on decision-making under conditions of severe uncertainty, the use of expertise, and scientific modelling, especially as a source of evidence for decisions. 

Here is a video of me describing some challenges with using models to support Covid-19 decision making, for a non-expert audience. 

I did my PhD in philosophy at the London School of Economics, working with Roman Frigg and Richard BradleyA copy of my CV is available here.

I am from Johannesburg, South Africa, but spent most of the 2010s living in the UK.
