Scientific biography

Training and professional positions

During his studies in Basel, Roland Buser was first personal scientific assistant to Alexander Markowitsch Ostrowski at the Mathematical Institute of the University of Basel (1967-69). From 1970 he worked as a doctoral student and research assistant at the Astronomical Institute of the University of Basel ( Uli W. Steinlin and Wilhelm Becker ) and spent several months of observation and research at the observatory of the University of Bonn on the Hohen List / Eifel (with Edward Geyer and Waltraut Seitter ) and at the Royal Observatory Edinburgh (with Kashi Nandy ). After receiving his doctorate, he deepened his studies in galactic structure as a postdoctoral fellow with Ivan King at the University of California at Berkeley (1975-77) and as a visiting associate with Bev Oke , Jim Gunn and Jesse Greenstein at the California Institute of Technology in spectrophotometry and multidimensional classification the stars (1977).

After that, Roland Buser was initially a research assistant at the Astronomical Institute of the University of Basel, where he completed his habilitation in 1981 and became a private lecturer in astronomy. From 1985 to 1986 he was appointed to the Space Telescope Science Institute in Baltimore (USA) as a scientific advisor to NASA (National Aeronautics and Space Administration) and AURA (Association of Universities for Research in Astronomy) and was appointed after his return to Switzerland in 1990 appointed Associate Professor for Astronomy at the University of Basel. From 1989 to 1997 he also held a permanent one-month visiting professorship at the Observatoire Astronomique and the Université Louis Pasteur in Strasbourg . As part of the professorial exchange program Switzerland-Austria and international cooperation with Egypt and Turkey, he also held visiting professorships at the Universities of Vienna , Graz and Innsbruck (1996) as well as at the Helwan Observatory in Cairo (1996) and at the University of Istanbul (1994) . Roland Buser has been emeritus professor in the Department of Physics at the University of Basel since 2010.

Research projects and international cooperation

Roland Buser's main area of ​​work was synthetic photometry [see writings: 1-6, 11, 15] and its extensive application in galaxy research [see writings: 7-10, 12-14, 16]. In international cooperation and with his doctoral students and postdocs, he developed the first stellar spectral library that was able to meet the growing demands of so-called development synthesis. This complete database of theoretical but empirically (ie based on observations) calibrated star spectra became known and widely used worldwide under the name BaSeL (for Basel Stellar Library). In his own group and with long-term employees from the USA, China, France, Venezuela, Brazil and Turkey, Roland Buser used BaSeL to research the formation, structure and chemical development of star clusters and the Milky Way up to the galaxies on Edge of the observable universe.

Membership and functions in professional societies

During his time as an active researcher, Roland Buser was a member of several national and international professional societies and organizations and in some of these he held various offices:

  • Swiss Academy of Natural Sciences (SANW)
  • Swiss Society for Astrophysics and Astronomy (SGAA, 1996–99, Office: President)
  • Swiss Commission for Astronomy (SKA, 1988–94, Office: President)
  • International Astronomical Society (AG)
  • International Astronomical Union (IAU), IAU Commissions 25 (Stellar Photometry) and 45 (Star Classification)
  • Chairman of the Synthetic Photometry Working Group of IAU Commissions 25 and 36 (Theory of Star Atmospheres) (1988–96)
  • Observatory Committee of the ESO (European Southern Observatory, 1988-92)
  • Philosophical Society Basel.

philosophy

As an astronomer, Roland Buser is not only a natural scientist, but also a philosopher . He sees natural philosophy as a field of knowledge that encompasses the horizon in which every natural science must be questioned and reflected on in terms of its basis, legitimation and objectives. In his book “Man in the Cosmos”, the need to increasingly transcend conventional subject boundaries in the direction of interdisciplinarity and transdisciplinarity is emphasized. The so-called individual or special knowledge of astronomy and the classical natural sciences (astronomy, physics, chemistry etc.) is deliberately developed in the broader context of the biological and humanities.

Current activities

Roland Buser currently offers comprehensible lectures and courses on astronomy, cosmology , cosmic evolution, peace research and epistemology, for example at the adult education center in Basel.

Awards

In 2018 Roland Buser received the Basel-Landschaft Culture Prize .
