Short Bio: I am a postdoc at the University of Queensland in Brisbane. My mentors are Masoud Kamgarpour, Peter McNamara and Tony Licata. Before this I was a postdoc at the Einstein Institute of Mathematics in Jerusalem where my mentor was David Kazhdan. During 2016-2017 I was a postdoc at the Max Planck Institute in Bonn. I graduated in 2016 from Stanford University where I was a student of Daniel Bump.
Research: My research is in representation theory. Some keywords: representation theory of p-adic groups, Whittaker functions, metaplectic groups, quantum groups, coideal subalgebras, Lie (super)algebras, lattice models and the Yang-Baxter equation/reflection equation, quantum invariants, polynomial functors, categorification.

Seminar on p-adic loop groups: I am currently organizing a seminar on p-adic loop groups. The syllabus is here.
QFT seminar: I have organized a seminar on lattice models and applications at UQ in the first semester of 2019. The syllabus, program and some lecture notes can be found here.
I have mentored Gavrilo Sipka during a vacation research summer project. The project dealt with fusion categories and quantum groups at a root of unity. You can find more info about the project and the report that Gavrilo wrote here.
