Who is Klaus Hepp?

Klaus Hepp is a German-born Swiss theoretical physicist working mainly in quantum field theory. Hepp studied mathematics and physics at Westfälischen Wilhelms-Universität in Münster and at the Eidgenössischen Technischen Hochschule in Zurich, where, in 1962, with Res Jost as thesis first advisor and Markus Fierz as thesis second advisor, he received a doctorate for the thesis and at ETH in 1963 attained the rank of Privatdozent. From 1966 until his retirement in 2002 he was professor of theoretical physics there. From 1964 to 1966 he was at the Institute for Advanced Study in Princeton. Hepp was also Loeb Lecturer at Harvard and was at the IHÉS near Paris.

Hepp worked on relativistic quantum field theory, quantum statistical mechanics, and theoretical laser physics. In quantum field theory he gave a complete proof of the Bogoliubov–Parasyuk renormalization theorem. Since a research stay 1975/6 at MIT he also worked in neuroscience.
