quantum field theory In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines Field theory (physics), field theory and the principle of relativity with ideas behind quantum mechanics. QFT is used in particle physics to construct phy ...

. He studied physics at the University of Hamburg from 1953 to 1958 and received his PhD there in 1963 on the topic of "Theory of Infraparticles". From 1959 to 1961 he was a research associate at the University of Illinois and 1963–74 at the Institute for Advances Studies, Princeton. He was then associate professor at the University of Pittsburgh (1964-1970) and Full Professor at the Free University of Berlin (1970-1999). He held visiting positions at USP, São Paulo, Brazil (1971/72), at CERN, Geneva, Switzerland (1976/77), and at the Pontifical Catholic University (PUC) in Rio de Janeiro, Brazil (1979/80). Furthermore, he was a visiting professor at CERN (1985/1986) and at the Math. Dept. of UC Berkeley (1992). Since 1999 he is emeritus professor at the Institute for Theoretical Physics at the Freie Universität Berlin and visiting professor at the Centro Brasileiro de Pesquisas Físicas (CBPF), Rio de Janeiro, Brazil.
