C*
In 1990, Popa was an invited speaker at the International Congress of Mathematicians (ICM) in Kyoto, where he gave a talk on "Subfactors and Classifications in von Neumann algebras". He was a Guggenheim Fellow in 1995.[2] In 2006, he gave a plenary lecture at the ICM in Madrid on "Deformation and Rigidity for group actions and Von Neumann Algebras".[3] In 2009, he was awarded the Ostrowski Prize, and in 2010 the E. H. Moore Prize.[4] He is one of the inaugural fellows of the American Mathematical Society.[5] In 2013, he was elected to the American Academy of Arts and Sciences.
