About | 余


Here’s a recent photo of me taken by my friend at Wuzhen.



I am currently at Room W915, 567 Yangsi Road (W), Pudong New District, Shanghai.

I can be reached via [my last name]@[my first name].me.

Alternatively, write to [my first name].[my last name]@nyu.edu.

My phone number is +1 (217) 377-uv, where u and v are the solutions to the equation x2-181x+8190=0, with u>v.

Here’s the link to my personal Zoom meeting room.


I am the executive producer of the film Before Firework, directed by my friend Xueyang Niu. I could offer some humble support for independent filmmakers, early-career authors or young artists, currently maybe for those based in Shanghai. I have a personal preference over dramas and romance novels though. Just let me know.

I occasionally serve Omakase menus for my friends at home. I also serve Sukiyaki at times, known as Ruaruakawa. Thanks to ScampiBunny for this name.

Something for my love, and something for my life.

Research | 索


My research interests lie in probability theory and mathematical physics.

Random geometry

I am interested in imaginary geometry, and its relation to Liouville quantum gravity and conformal field theory.

Spin systems

  • Currently, I am interested in general spin systems.

  • From 2020–2021, I gave an geometric interpretation of the collective dynamics for magnetic solitons with Oleg Tchernyshyov.

Cat™ theory

I study a special cat™, MuonCamus, by observing how she interacts with rest of the world.
