Currently Full Professor at IHES ([Bures sur Yvette]?, France).
Specialist of [Von Neumann Algebra]?s, he succeeded in completing the classification of factors of these objects. He was awarded the [Fields medal]? in 1982.
The remarkable links between this subject, the tools he and others devised to tackle the problem and other subjects in theoretical physics, particle physics, differential geometry, made him emphasize [Noncommutative Geometry]? (name of his major book to date).
