Olle Häggström

Professor at Chalmers, Mathematical Sciences, Applied Mathematics and Statistics

Olle Häggström is a professor of mathematical statistics. During July 2011 - June 2014 he served as head of the mathematical statistics division, a duty he has now handed over to his colleague Serik Sagitov. Liberated from that, he now hopes to get more time for what he always considered his primary tasks: research, research supervision, teaching and popular science. His main research interest is probability theory, where typically his goal is to understand how the behavior of a system consisting of very many small components depends on the properties of the components. Besides this, his intellectual interests are broad, currently mostly in the directions of philosophy, climate science and futurology.
