Education and careerEdit

Benz was educated at ETH Zurich where he was awarded a Diploma in Theoretical Physics in 1969. He then went to Cornell University in Ithaca, N.Y. USA, where he received a PhD in astrophysics for his research on the acceleration of the solar wind in 1973.[2] After his return to ETH Zurich he studied plasma physical processes in the solar corona.[3] He led a research group on radio astronomy from 1974 to 2010. In 1974 he became a lecturer at the Physics Department and in 1993 he was nominated professor for physics with focus on astrophysics. He is professor emeritus at ETH Zurich since 2010 and continues to work at the Institute for Astronomy and part-time at Fachhochschule Nordwestschweiz (FHNW) in Windisch, Switzerland.

Research and achievementsEdit

Benz is well known for his observations and interpretation of the solar radio emission(ultra high frequency) [4][5] and particle acceleration in solar and stellar flares with several hundred scholarly publications. The Güdel-Benz relation between radio and X-ray emission of flares was named after him.[6] More recently, Benz studied star formation using molecular line observations by the Herschel Space Observatory. Benz presided several scientific committees, such as the Swiss Society for Astrophysics and Astronomy (1999-2002) and Division II (Sun and Heliosphere) of the International Astronomical Union (2000-2003).

To the public at large, Benz is known for his numerous presentations on astronomy at the popular level, most prominently on Swiss television and radio since 1979, as well as for his books on the dialog between science and religion. He received an honorary doctorate from the Faculty of Theology of the University of Zurich [7] for his merits to the interaction between science and theology, in which he stresses the differences between scientific and religious perception.[8] The University of the South (Sewanee, TN, USA) awarded him 2017 an honorary doctor's degree in Science "for his distinguished contributions to astronomical inquiry and for his illuminating, interdisciplinary reflections".[9]
