Yahui Qu

I’m a mathematics Ph.D. student at University of Wisconsin–Madison, where I’m fortunate to be advised by Hao Shen and Benedek Valkó. Previously, I obtained my B.S. in Applied Mathematics from the Chinese University of Hong Kong, Shenzhen. My email address is yqu45 at wisc dot edu. I expect to be on the job market in Fall 2027.

Research

I’m interested in Probability, especially

  • Random Matrix Theory: I work on problems about beta ensembles using the random operator approach.
  • Stochastic Partial Differential Equation: I apply regularity structures to nonlinear SPDEs related to quantum field theory problems.

Awards

  • Bung-Fung Lee Torng Award, Summer 2025.

    I am grateful for the support of this fellowship, with which I was able to participate in the program Probabilistic Methods in Quantum Field Theory at the Hausdorff Research Institute for Mathematics in summer 2025. This ultimately led to our work on the scaling limit of the 3D abelian Yang–Mills Langevin dynamics.

Teaching

I am currently the instructor of Math 112: College Algebra in Fall 2026. In addition, I was the instructor of Trigonometry in Fall 2024 and have been the teaching assistant for courses including Calculus, Linear Algebra, Differential Equations, Discrete Mathematics, and Cryptography.

Outreach

  • I’m the president of the SIAM seminar at the University of Wisconsin–Madison. Our seminar aims to provide young researchers in applied mathematics and related fields with a platform to share their work and explore interesting problems, while also helping mathematics graduate students build connections with professionals in technology, finance, and other industries.
  • I am a co-organizer of Gender Minorities in Math at Wisconsin (GmMaW) at the University of Wisconsin–Madison.
  • I was a co-organizer for the Graduate Student Probability Conference, September 1-2, 2024.
  • I served as a graduate student mentor for the Madison Experimental Mathematics Lab during Spring 2024, Spring 2025, and Spring 2026.
