Areas of interest
A random 3-dimensional section of the 1000-cube © Jos Leys
I'm interested in the following topics
Convex geometry, especially high-dimensional. This field is sometimes called Asymptotic Geometric Analysis.
Quantum information theory and its interplay with the former.
Random matrices.
Alice and Bob meet Banach (book written with Stanislaw
Szarek)
