Research interests

Spectral theory of canonical systems and related differential operators (especially Schrodinger–,

Jacobi–, and Krein-Feller operators), de Branges Hilbert spaces of entire functions and their

applications, geometry and operators in indefinite inner product spaces (especially symmetric

operators and their selfadjoint extension), interpolation- and extrapolation- problems (especially

power moment problems), convex algebras and their applications in computer science, functional

analysis, complex analysis, and algebra in general.
