His research focus was on quantum electronics and infrared physics , in particular in the spectroscopy of condensed matter, atmospheric physics and building physics .


Kneubühl studied physics at the ETH Zurich with a Master of Science degree in 1955 with Georg Busch and Karl Alexander Müller and received his doctorate in 1959 with Hans H. Günthard .

In 1963 he completed his habilitation in physics, was assistant professor from 1966 to 1969, associate professor until 1971 and since 1972 professor of physics at the ETH in Zurich. From 1978 to 1980 he headed the Institute for Quantum Electronics and since 1986 the Laboratory for Infrared Physics. He was a member of numerous advisory boards of international conferences on quantum electronics and infrared physics, as well as president of the international conferences on infrared physics 1 to 6 in Zurich and Ascona (1975, 1979, 1984, 1988, 1993, 1994).
