#### Research interests

Analysis and Operator Theory, and various connections
between Operator Theory, Matrix Theory and Mathematical Systems
Theory. In particular, Wiener-Hopf integral equations and Toeplitz
operators, their nonstationary variants, and other structured
operators, such as continuous operator analogs of Bezout and
resultant matrices. State space methods for problems in analysis.
Also metric constrained interpolation problems and completion
problems for partially given operators, including relaxed commutant
lifting problems.
