Jiyuan Zhang (张纪元)

I became an associate professor in South China University of Technology (华南理工大学), Guangzhou, China since 2025. From 2022 to 2025 I was a post-doc researcher in KULeuven. In 2022 I obtained my PhD degree under supervision of Peter Forrester and Mario Kieburg.

I am hiring post-docs. Please contact me via jiyuan.zhang@scut.edu.cn if you are interested.

Research Interests

Random Matrix Theory: I study mostly random matrix models with invariance structure, for example, they are invariant under conjugation of the unitary group. Please see [ArXiv:2007.15259] for a structural property specifically given by unitary invariance.

Free Probability Theory: I am interested in the harmonic/analytic theory of free probability theory, including studies around the R and S transforms, free Levy-Khintchine formula, and connections with symmetric functions such as the multivariate Bessel function. Please refer to [ArXiv:2508.21349] on this topic .

Determinantal Point Process: I am interested in exactly solvable determinantal point processes. Most of them possess a double integral formula which allows for an asymptotic analyis. Please see [ArXiv:2012.11993] for some contributions in this direction.
