I will join IGP/IMFP, USTC as a post-doc at the end of Sept 2025.

From September 2022 to July 2025, I was PhD student at Institut Fourier under the supervision of Gérard Besson and Hervé Gaussier. I defended my thesis on 11th July 2025.

From September 2021 to June 2022, I was a master's student at Institut Fourier under the supervision of Gérard Besson.

My research area is complex geometry and geometric analysis.

I am interested in problems related to scalar curvature, Kähler-Ricci flow, complex Monge-Ampère equations, and extremal Kähler metrics.


(Pre-)Publications

[1] Homological 2-systole in Kähler surfaces fibered over an elliptic curve, in preparation, 2025

A short note that will appear soon.

[2] Rigidity of complete Kähler-Einstein metrics under cscK deformations, preprint, latest version, 2025

My goal (beyond the scope of this note) is to identify verifiable criteria that separate cscK metrics from Kähler-Einstein metrics on complete manifolds. But I am so weak. (。•́︿•̀。)

[3] The Kähler-Ricci soliton on bounded pseudoconvex domains, arXiv:2412.03345, submitted, latest version, 2024

There are some typos in the arXiv version and the proof of Proposition 3.1 is incorrect, while the statement that the soliton is expanding is still true by our assumption. Please see the revised version in the above link.

What's a mathematician to do?

"It seems entirely plausible that, with all the tremendously clever people working so hard on mathematics, there is nothing left for someone such as myself (who would be the first to admit they do not have any special talent in the field) to do. Perhaps my value would be to act more like cannon fodder? Since just sending in enough men in will surely break through some barrier."
