My Ph.D. advisor was
John B. Conway, his advisor was Herron Collins,... see my Mathematical Lineage

My research area is
analysis. I specialize in operator theory and complex
analysis. More precisely, I study linear operators on
Hilbert space that are "close to normal operators", such as
subnormal and hyponormal
operators. One topic of interest involves the study of
the cyclic behavior of adjoints
of subnormal and hyponormal
operators. Recent work involves
invariant convex sets for linear operators,
convex-cyclic operators and convex-polynomial
approximation.
