Ariel Goobar

Ariel Goobar is Professor of Physics at Stockholm University, where he has held a chair since 1999, and Director of the Oskar Klein Centre for Cosmoparticle Physics since 2022. He also directs the EDUCATE Centre at OKC. He earned his PhD in particle physics from Stockholm University in 1992 with a thesis on Higgs boson searches at the DELPHI experiment at CERN, before moving to Lawrence Berkeley National Laboratory, where he joined the Supernova Cosmology Project. His research focuses on observational cosmology, particularly the use of Type Ia supernovae as cosmological distance indicators, gravitationally lensed supernovae, and the electromagnetic counterparts of gravitational-wave sources. He is a long-standing member of the Supernova Cosmology Project, whose discovery of the accelerating expansion of the universe led to the 2011 Nobel Prize in Physics, and contributes to major time-domain surveys including the Zwicky Transient Facility and the Vera C. Rubin Observatory (LSST). His distinctions include the 2015 Breakthrough Prize in Fundamental Physics, the 2007 Gruber Prize in Cosmology, and the 2004 Gustafsson Prize. He was elected to the Royal Swedish Academy of Sciences in 2016.
