Prof. Dr. Lars Bergström
Corresponding Council Member
Professor of Theoretical Physics, Stockholm University; Secretary of the Nobel Committee for Physics 2004-2015
Lars Bergström earned his Ph.D from the Royal Institute of Technology in Stockholm, Department of Theoretical Physics, in 1981, with a thesis on interactions of quarks and gluons for bound states including effects of special relativity. Afterwards, he spent two years at CERN, Geneva, working further on theory of elementary particles. After joining Stockholm University, Lars Bergström specialised in astrophysics and cosmology. He is particularly interested in the interplay between fundamental particle physics and cosmology, for example in modelling the still unknown dark matter of the universe. In this field he started the Oskar Klein Centre (OKC), an excellence centre where scientists develop theory and experiments around two of the most fundamental questions of present-day cosmology: dark matter and dark energy.
Further recent activities include the analysis of data gathered from the Fermi Gamma-ray Space Telescope since its launch in 2008. Current interests of Prof. Bergström related to the OKC include supernova cosmology and studies of the Galactic centre, where a black hole of 4 million solar masses lurks and from where possible signals from dark matter can be studied. Prof. Lars Bergström is the author of about 200 research papers and six books, including the university textbook “Cosmology and Astroparticle Physics” (with his colleague A. Goobar), published by Praxis/Springer Verlag in 2004.
Prof. Bergstöm was Secretary of the Nobel Committee for Physics 2004-2015 and is a member of the physics class of the Royal Swedish Academy of Sciences. He has been a corresponding member of the Council for the Lindau Nobel Laureate Meetings since 2004 and, as a scientific chairperson, co-organises the scientific programme of the Lindau Meetings dedicated to physics.
