My main research interests are in the representation theory of finite dimensional algebras. This area was born of a desire to understand how a finite number of linear transformations can act simultaneously on a vector space. Over the last forty years, a well-developed theory has emerged; the Auslander-Reiten theory now understands the representations of an algebra as the study of the classification of the indecomposable modules over that algebra and the homomorphisms between them. My current focus is the relationship between the Auslander-Reiten theory and the recently developed Gabriel-Roiter theory, which provides an alternative classification mechanism for the module category.
I have served three times as a Volunteer Lecturer at the Royal University of Phnom Penh (RUPP) in Cambodia. During each of my first two visits, I taught a course in Ordinary Differential Equations. My third visit was in June, 2012, when I taught a course in Group Theory. The Volunteer Lecturer Program is supported by the National Academy of Sciences and focuses on scientific capacity-building in Cambodia and other developing countries. Volunteer lecturers from the USA, France, Japan, and other countries collaborate with RUPP to offer a masters program in mathematics. More information about the program can be found on their website: http://sites.nationalacademies.org/pga/biso/IMU/PGA_050583
