Research Interests
My research area is geometric representation theory. My advisor is David Ben-Zvi.
One of my current research projects involves a quantization of hypertoric varieties. The quantization features a certain algebra of q-difference operators on affine space. When q is a root of unity, this algebra gives rise to an Azumaya algebra on the muliplicative hypertoric variety, via a Hamiltonian reduction procedure. We are currently working on a localization theorem and on conditions for finite homological dimension. Various aspects of this work are joint with or guided by David Jordan, Nicholas Cooney, and Kobi Kremnitzer. Please email me if you would like to see a draft of this work.
I co-organized a workshop on Yangians and quantum loop algebras, which was held near Austin in May 2014.
During Spring 2012 and part of Summer 2012, I co-organized a learning seminar on categorical representation theory related topics.
