Research Interests:

My research is in operator theory on Hilbert spaces.  Much of my research has been in function-theoretic operator theory (subnormal operators, composition operators).  I also study operator algebras associated with a single operator, such as the commutant of an operator or the algebra generated by an operator.

Recent Publications and Preprints:

1. Separating vectors and extensions of operators (with D. Han, D. Larson, Z. Pan).  Preprint available.
2. Commutative radical Banach algebras (with J. Peters).  J. Operator Th. 42(1999), 405-424.
3. Extensions of bitriangular operators (with D. Larson), Integr. Equat. Oper. Th. 25(1996), 216-223.
4. Extensions of normal operators (with D. Larson), Integr. Equat. Oper. Th. 20(1994), 225/234.
5. Separating vectors versus strictly separating vectors (with E. Azoff, L. Ding), PAMS 124(1996), 3135.3142.
