Here is my CV if you are interested.

My research interests lie in Ring Theory (both noncommutative and commutative rings) and Noncommutative Geometry (including noncommutative algebraic geometry). I am also interested in cases where these ideas intersect with the study of category theory, operator algebras, and quantum physics.

Here are some preprints of my papers:- Infinite-dimensional diagonalization and semisimplicity (with Miodrag C. Ivanov and Zachary Mesyan), submitted. (Also available at arXiv:1502.05184.)
- A prime ideal principle for two-sided ideals , submitted. (Also available at arXiv:1501.06808.)
- On discretization of C*-algebras (with Chris Heunen), submitted. (Also available at arXiv:1412.1721.)
- Skew Calabi-Yau triangulated categories and Frobenius Ext-algebras (with Daniel Rogalski and James J. Zhang), to appear in Transactions of the AMS. (Also available at arXiv:1408.0536.)
