Research

My research interests are in operator algebra and operator theory. In particular, most of my papers are about limit algebras, infinite-dimensional operator algebras that are limits of finite-dimensional algebras. In spite of being "almost finite-dimensional", they have some quite surprising properties.

Conferences and events I help or have helped organize

• 2025 East Coast Operator Algebras Symposium
• 2024 Great Plains Operator Theory Symposium
• Nebraska-Iowa Functional Analysis Seminar a local semi-annual conference in functional analysis.
• Special meeting of the Nebraska-Iowa Functional Analysis Seminar held in conjunction with the 2018 Howard
• Rowlee Lecture given by Ruy Exel, which I organized jointly with David Pitts.
• Nebraska Conference for Undergraduate Women in Mathematics
• Nebraska IMMERSE This is a summer program for students starting graduate school in the fall.
• Recent Progress in Operator Algebras, a Special Session at the 2011 Lincoln, NE meeting of the American Mathematical Society, which I organized jointly with David Pitts.
• 2007 Great Plains Operator Theory Symposium
• Recent Progress in Operator Algebras, a Special Session at the Lincoln, NE meeting of the 2005 American Mathematical Society, which I organized jointly with David Pitts.
• Coordinate Methods in Nonselfadjoint Operator Algebras, a workshop held December of 2003 at the Banff International Research Station for Mathematical Innovation and Discovery, which I organized jointly with Michael Lamoureux of the University of Calgary.
