GNTRT: I am organizing the Geometry, Number Theory and Representation Theory seminar at University of Alberta. The focus of the first part of the seminar will be on the representation theory of p-adic groups and Hecke algebras.
WiSe: I am currently organizing the What is ...? seminar at UQ. If you would like to be on the mailing list, please send me an email.
Conference: Ole Warnaar and I organized a conference on integrable systems. You can find slides and youtube videos of the talks on the conference webpage.
Short Bio: I am a postdoc at the University of Alberta with Manish Patnaik. I used to be a postdoc University of Queensland. Before this I was at the Einstein Institute of Mathematics in Jerusalem where my mentor was David Kazhdan and during 2016-2017 I was 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, Hecke algebras, metaplectic groups, quantum groups, quantum symmetric pairs, Lie (super)algebras, algebraic combinatorics and special functions, integrable lattice models and the Yang-Baxter equation/reflection equation, quantum invariants, polynomial functors, categorification.
A poster on representation theory of p-adic groups and quantum affine groups/symmetric pairs: poster.

Teaching and seminars:
I taught a reading course on Linear Algebraic Groups following Springer's book at UQ.
I co-taught Advanced Algebra (Math 4301) at UQ in Semester 2, 2019. Homeworks and syllabus can be found on learn.uq.edu.au
Seminar on p-adic loop groups: I organized a seminar on p-adic loop groups. The syllabus is here.
QFT seminar: I 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 am a co-adviser for Bailey Whitbread's honours thesis. The main adviser is Masoud Kamgarpour.
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.
