My research focuses on ring theory (both noncommutative and commutative rings) and noncommutative geometry (including noncommutative algebraic geometry). I am often interested in cases where these ideas intersect with the study of category theory, operator algebras, and quantum physics.

Here are some slides from selected talks that I have given:

- The spectrum problem for noncommutative rings and algebras, at the Oxford Advanced Seminar on Informatic Structures, May 22, 2015.
- Skew Calabi-Yau algebras and homological identities, at the Joint International Meeting of the American Mathematical Society and the Romanian Mathematical Society, June 30, 2013.

Resources in noncommutative algebra:

- ncag.info (includes a list of upcoming conferences in noncommutative algebraic geometry)
- Women in Noncommutative Algebra and Representation Theory
