Ciprian Foias

Born in Reșița, Romania, Foias received his doctorate from the University of Bucharest in 1962, under supervision of Miron Nicolescu. He taught at his alma mater (1966–1979), Paris-Sud 11 University (1979–1983), and Indiana University (1983 until retirement). Beginning in 2000, he was a teacher and researcher at Texas A&M University, where he was a Distinguished Professor.

The Foias constant is named after him. Foias is listed as an ISI highly cited researcher.[1]

Together with Sz-Nagy, Foias proved the celebrated Commutant lifting theorem.

He died in Tempe, Arizona on March 22, 2020.[2]
