Sorin Teodor Popa is a Romanian American mathematician working on operator algebras. He is a professor at the University of California, Los Angeles.Biography
Popa earned his Ph.D. from the University of Bucharest in 1983 under the supervision of Dan-Virgil Voiculescu. He has advised 15 doctoral students at UCLA, including Adrian Ioana.In 1990 Popa was an invited speaker at the International Congress of Mathematicians in Kyoto, where he gave a talk on "Subfactors and Classifications in von Neumann algebras". He was a Guggenheim Fellow in 1995. In 2006 he gave a plenary lecture at the ICM in Madrid on "Deformation and Rigidity for group actions and Von Neumann Algebras".. In 2009 he was awarded the Ostrowski Prize, and in 2010 the E. H. Moore Prize. He is one of the inaugural fellows of the American Mathematical Society.Selected publications
