As of September 2016, I am a postdoc in the Hausel group at IST Austria. Contact information here. New website coming soon!

Research Interests

My research lies at the intersection of representation theory, algebraic geometry, and quantum algebra. I am currently thinking about asymptotics of quantum groups, and the quantum analogues of the wonderful compactification, the Vinberg semigroup, and related objects. Another research direction concerns the interaction between group-valued Hamiltonian reduction and Azumaya phenomena that occur at quantization at root of unity. Of particular interest are multiplicative quiver varieties as instances of the general framework of Frobenius quantum moment maps. I am also interested in deformations of category O for rational Cherednik algebras and relations to sheaves on moment graphs.

My advisor is David Ben-Zvi.
