Most of my scientific life I worked in Banach space theory. My early research
concern Banach spaces with the Random-Nikodym property, differentiability of
Lipschitz mapping between Banach spaces, uniform and Lipschitz classification
fo Banach spaces and generalizations of the Mazur-Ulam theorem. More
recently, I study random quotients of finite dimensional Banach spaces. This
led to constructions of finite dimensional Banach spaces with relatively
"few" well bounded linear operators and resulted in solving several problems
in both local and structural theory of Banach spaces.
