I am a PhD candidate in mathematics at Leiden University, working in the field of noncommutative geometry. My supervisor is Prof. Dr. Bram Mesland.
From 2013 to 2018, I studied physics and mathematics at Peking University, China. From 2018 to 2021, I studied mathematics at Georg-August-Universität Göttingen, Germany, specialising in noncommutative geometry and its application in topological insulators. I wrote my master thesis under the supervision of Prof. Dr. Ralf Meyer.
I study the application of noncommutative geometry to index theory and mathematical physics. Work of mine in progress is devoted to understanding topological insulators using tools from noncommutative geometry and C*-algebras, following the pioneering work of Jean Bellissard. Another keen interest of mine is unbounded KK-theory, a novel framework for Connes' noncommutative differential geometry initiated by Bram Mesland, soon joined by brilliant mathematicians including Walter van Suijlekom, Jens Kaad, Simon Brain, Adam Rennie and many others.
Besides mathematics, I am also an enthusiastic long-distance runner.
2024 Spring Semester: I am tutoring the Dutch national mastermath course "Operator Algebras" taught by Martijn Caspers and Bram Mesland. The noncommutative geometry research group of Leiden university is running a research seminar on NCG and related topics.
I am a maintainers of NCG-Leiden (together with Yufan Ge and Francesca Arici), a webpage collecting and announcing the information of local NCG seminars at Leiden University. In 2024 spring semester, Francesca Arici and Bram Mesland are running a research seminar on Wednesdays from 15:15-16:15. If you want to be added to the mailing list for this seminar, please contact Francesca Arici or Bram Mesland.
In the upcoming month (March 2024), Adam Rennie will give a mini-course on connections and curvatures in NCG, based on ongoing work of him and Bram Mesland.
In previous semesters, we have run reading seminars on noncommutative geometry of foliations (2023 fall), groupoid C*-algebras (2022 fall) and KK-theory (2022 spring).
I have taken notes for several lectures and seminars. Some of them are below. They may be incomplete and contain mistakes. Please use at your own risk.
I am an eager runner, and a learner in German and Dutch.
I enjoy long-distance running. As an undergraduate student at Peking university, I was a member of PURA (Peking university runners' association). I paused running for several years but rediscovered my passion during the pandemic in 2021. Despite of those enumerous annoying injuries, running brings me far more pleasure and confidence.
Until now I have participated in (and finished) one half-marathon. More to achieve in 2024.
Ich lerne Deutsch und Niederländisch. Ich interessiere mich auch für die Geschichte der germanischen Sprachen.
