I happened to be travelling through Brussels, so I stopped by Ghent, the world hotspot for research into imprecise probabilities, and setup an interview with Gert de Cooman. Gert has been working in imprecise probabilities for more than twenty years, is a founding member and former President of SIPTA, the Society for Imprecise Probability: Theories and Applications, and has helped organize many of the ISIPTA conferences and SIPTA Schools.
Topics include fair betting rates, Dutch books, Monte Carlo methods, Markov chains, utility, and the foundations of probability theory. We had a rich, wide-ranging discussion. You may need to listen two (or more!) times to process everything.
