Prizes: Young Scientist Award in the area of Mathematics from Academia Europaea (for fSU researchers), 1998.
Research Interest
Most of his research is devoted to spaces of analytic functions of a complex variable. Typically, the functions live on the unit disk and are well-behaved, in a sense, near/on its boundary, the unit circle. Various specific interpretations of "well-behaved", such as a natural growth restriction or some kind of boundary smoothness, give rise to important function spaces with nice properties, and I have studied some of these.He is also concerned with certain types of linear operators (e.g., the so-called Toeplitz and Hankel operators) acting on such spaces.
