I am currently a member at IAS during academic year 2023–2024. Starting from Autumn 2024 I will be a postdoc at University of Michigan.
I earned my PhD from the University of Chicago in June 2023, under the supervision
of Prof. Ngô, Bảo Châu.
My real name is hard to pronounce for a typical English speaker, so I go by the name of Griffin.
My research interest lies in the junction between representation theory, algebraic geometry and number theory.
- Current research involves multiplicative Hitchin fibration and (twisted) endoscopy theory. I am trying to provide a unified proof of the fundamental lemmas in endoscopy theory (from standard to the yet unproven twisted weighted) directly at group level.
- The first stage of this project is the standard fundamental lemma, originally proved by my advisor for Lie algebras. This stage is close to completion and a WIP-version of preprint is available upon request.
My thesis may be found on ProQuest, which essentially contains a 90 percent completion of the said project due to time constraint. However, there has been some important development since its submission. Some non-trivial errors have been found and fixed as well.
- Qualification Topic A summary of Godement-Jacquet
theory. A full note can be found here.
- A summary of Langlands and Shelstad’s paper on the definition of endoscopic transfer factors.
- A note on Harder-Narasimhan filtration for reductive groups. This is the note of my talk at the BunG Seminar at the University of Chicago in Winter 2023.
- A short note on p-adic integrals in algebraic setting.
- A tiny 3-page note recorded during Ngô’s seminar explaining
the most basic part of the Hitchin fibrations, which I (at the time) found both concise
and conceptually satisfying.
PossiblyDefinitely forever) unfinished notes for V. Ginzburg’s class Geometric
Satake in Spring 2018.

- I’m a gamer.
The games I have been
wasting hundreds of hours on enjoying
- math (currently a professional player)
- The Legend of Zelda Breath of the Wild (I found all 900 Korok seeds and completed Trial of the Sword in Master Mode without using glitch :)
- The Legend of Zelda Tears of the Kingdom (ongoing)
- Fire Emblem Three Houses and Fire Emblem Engage
- I delivered a lecture about competitive Pokémon battle at the University of Chicago during my teaching training.
- I also conduct some casual research in knot theory, during which I found a
broken link on Jon DeWitt’s page.
Pretentious meaning behind my logo
The name Griffin comes from the mythological creature griffin (or gryphon,
or griffon). My first name means "courage", and my last name means "king" (which is nothing special since 99% of the Chinese are descendants of a handful of ancient rulers; probably also true for other civilizations if I have to guess),
both of which a griffin heraldically befits. The logo is my own design. It
is a deformation of the Chinese characters for my name "驍(Xiāo)王(Wáng)"
into a Griffin.
