Adrian Ioana

Adrian Ioana ( born January 18, 1981 in Târgu Jiu, Romania) is a Romanian mathematician who deals with von Neumann algebras, ergodic theory of orbits of groups and representation theory of groups.

Ioana 1997 received a first prize at the Romanian National Mathematical Contest in 1999 and a silver medal at the International Mathematical Olympiad. He studied mathematics at the University of Bucharest with the financial statements for 2003 and at the University of California, Los Angeles ( UCLA), where he received his doctorate in 2007 Sorin Popa ( Some rigidity results in the orbit equivalence theory of non- amenable groups). As a post-doctoral researcher Olga Taussky Todd, he was instructor at Caltech and from 2008 to 2011 Clay Research Fellow. From 2011 he was assistant professor at the University of California, San Diego. Since 2006 he is member of the Institute of Mathematics of the Romanian Academy of Sciences.

He proved that a countable discrete groups containing a copy of the free group uncountable allow many non- orbit- equivalent effects.

In 2012 he was awarded the EMS price for its impressive and deep work in the field of operator algebras and their connection to ergodic theory and group theory and for the solution of several important open problems in the deformation and rigidity theory of operator algebras, including a conjecture of Alain Connes on of Neumannalgebren without outer automorphisms ( eulogy ).
