Basic information:

I am an associate (with tenure-track) professor at Academy of Mathematics and Systems Science, Chinese Academy of Science since April of 2023. My research focuses on studying mathematical problems related to the theory of General Relativity, hyperbolic partial differential equations, and geometric analysis. 

I obtained my Ph.D. from Max Planck Institute for Gravitational Physics in July 2018, under the supervision of Lars Andersson, with research topic “Analysis on black-hole spacetimes” and PhD thesis entitled “Analysis of Teukolsky equations on slowly rotating Kerr spacetimes” with the highest grade “summa cum laude”.

After my Ph.D., I did my postdoc with Jérémie Szeftel in Laboratoire Jacques-Louis Lions at Sorbonne Université from 2018 to 2022 and an Alexander von Humboldt postdoc with Lars Andersson at Max Planck Institute for Gravitational Physics from 2022 to 2023.

I can be reached by email at firstname.familyname[AT]amss.ac.cn.
