Lárus Thorlacius received his PhD from Princeton University in 1989. After postdoctoral work at Stanford University and the Institute for Theoretical Physics at UC Santa Barbara he returned to Princeton as an assistant professor and has been a professor of physics at the University of Iceland since 1998. He served as the Director of Nordita, the Nordic Institute for Theoretical Physics, in Stockholm, 2008 - 2014. His field of research is theoretical high-energy physics, with emphasis on string theory and quantum gravity. He has worked extensively on theoretical problems involving black holes, including the black hole information paradox. In recent years his main focus has been on black hole physics in the context of gauge theory/gravity duality.
