About me
I am an Assistant Professor in Mathematics at POSTECH in Pohang, South Korea. I received my PhD in 2016 from Stanford University where I was a student of Daniel Bump. Between 2016 and 2023 I was a postdoc at the KdV Institute / University of Amsterdam (with Jasper Stokman, 2021-2023), University of Alberta (with Manish Patnaik, 2020-2021), University of Queensland (with Masoud Kamgarpour, 2018-2020), Hebrew University of Jerusalem (with David Kazhdan, 2017-2018) and the Max Planck Institute in Bonn (2016-2017).
Research
My interest is in representation theory (broadly interpreted to include connections with mathematical physics, number theory, algebraic combinatorics and geometry).
I am specifically interested in the representation theory of $p$-adic groups and their generalizations (like metaplectic groups or loop groups), their Hecke algebras and connections to quantum theory (quantum groups, quantum symmetric pairs, categorification, Kazhdan-Lusztig combinatorics etc.).
I also have a long standing interest in solvable lattice models and special functions appearing in algebraic combinatorics, representation theory and geometry.
For more information, see my publication list.
I am currently working on understading conncetions between quantum groups and metaplectic groups, c.f. my recent paper with Manish Patnaik. Recently, I also became interested in the Gaiotto conjectures and relative Langlands dualities.
If you feel like you have common interests, feel free to get in touch.
News
I will be in Singapore between January 4-17, 2026, where I'll give a lecture series on quantum groups in the relative Langlands program.
See events in representation theory at POSTECH.
Together with Sungmun Cho and Qirui Li, we organized a lecture series on relative Langlands at POSTECH.
