Joe Roussos

I am completing my PhD in philosophy at the London School of Economics, working with Roman Frigg and Richard Bradley

After that, I will be a postdoctoral researcher at the Institute for Futures Studies, in Stockholm. I am a part of the Climate Ethics project. 

I work on two related fields: (1) decision-making under conditions of severe uncertainty, and (2) scientific modelling, especially as a source of evidence for decisions. My recent work has focused on climate science, and in particular on the prediction of hurricanes striking North America.

More broadly, I am interested in the social epistemology of science: how it should be organised, and how it should interact with the rest of society. Much of my work can be characterised as formal epistemology (i.e., I use mathematical tools), though much of my interest is in non-ideal, messy situations in which our favoured formal tools fare poorly. 

A copy of my CV is available here.

I help organise the LSE’s Conjectures and Refutations seminar series.

Before beginning my PhD I worked as a management consultant for Bain & Co., and then in the strategy team for London-based property developers Lodha UK. I have a Master’s in theoretical physics from the University of Cambridge, and my undergraduate degree was in Physics and Philosophy at the University of the Witwatersrand.

I have also worked as a freelance consultant, on strategy, management and decision-making.
