I work for Voleon as a researcher in London.
I was a mathematician working in algebraic topology.
If you are interested in my transition to the industry, please don't hesitate to contact me.
I work in quantitaive finance. I like market anomalies, no matter if we can profit from it or not. I also find portfolio construction and impact modelling difficult but appealing.
I worked with Gergely and Honglu on applying reinforcement learning to algebraic geometry (see Projects).
I worked in algebraic topology, specializing in chromatic and equivariant stable homotopy theory. My research focused on technical computations (usually via spectral sequences), and the unexpected consequences and relations revealed by these computations.
Chromatic means you smash the object you are interested in into (colorful) pieces, study them, and then try your best to reassemble the pieces together.
Equivariant means you keep spinning the globe in your living room, and after an hour you realize that no matter how hard you spin it, the shape of the globe is more or less the same by looking at it from different angles.

Applying reinforcement learning (DQN and AlphaZero) to the Hironaka polyhedra game. The game gives a resolution of a singularity in a high-dimensional space.

In Spring 2021, I taught a hybrid seminar/course on the Hill-Hopkins-Ravenel solution of the Kervaire invariant one problem.
In Spring 2020, Hana Jia Kong and I organized an online reading seminar on THH.
In Spring 2020, Gijs Heuts, Yuqing Shi, and I organized a masterclass on exotic spheres.
I am a member of research staff in Voleon. I am based at London.
I was a postdoc at Aarhus University in Denmark, supervised by Gergely Bérczi.
I was a postdoc at the Max Planck Institute for Mathematics in Bonn, Germany from September 2021 to August 2023, supervised by Tobias Barthel.
I was a postdoc at Universiteit Utrecht in the Netherlands from January 2019 to August 2021. My mentor was Lennart Meier.
I was in the Isaac Newton Institute for the Homotopy Harnessing Higher Structures program from August 2018 to December 2018.
I was a graduate student at the University of Rochester under Doug Ravenel and defended my thesis in May 2018.
I was an undergraduate student at Zhejiang University under the guidance of Shiu-Chun Wong.
I travel, read books, and play video games when I have time or need distractions.
I am a fan of García Márquez, Hidetaka Miyazaki, and Hideo Kojima.
