Dr. Nassif Ghoussoub

Nassif Ghoussoub is a deep and prolific mathematician who is recognized as a world leader in the geometry of Banach spaces and in non-linear analysis. His work with Maurey connecting extremal properties of subsets with structural properties of the space led to the resolution of several long-standing problems in Banach space theory. In the area of non-linear analysis, he had pioneered new variational techniques which allow for the location and classification of saddle points. These results in turn have been used by Dr. Ghoussoub and others to make fundamental new discoveries in partial differential equations and geometry.
