Posdoctoral Associate in the Department of Mathematics @ Virginia Tech

Hello! I am a postdoctoral associate in the Department of Mathematics at Virginia Tech, working with Prof. Traian Iliescu. I earned my Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign in 2023, where I was advised by Prof. Paul Fischer. You can find more about me here.

My research focuses on the developement of data-driven reduced-order modeling for turbulent flows. In particular, I am working on modeling–constructing accurate and efficient data-driven ROMs, numerical analysis–proving fundamental mathematical properties, e.g., stability, consistency, convergence and parameter scalings, and numerical simulation–testing the new data-driven ROMs in the simulation of turbulent flows in engineering.

Upcoming Talks

  1. StabOp: A Data-Driven Stabilization Operator for Reduced-Order Modeling, ISCL Seminar Series, 19 March 2026. Hosted by Romit Maulik and Hokin Kim.
  2. Scalable Nonlinear Manifold Reduced-Order Models: Domain Decomposition and Cross-PDE Expressivity, SIAM UQ, 23 March 2026. Joint work with Xiaolong He, Ivan Zanardi, Alejandro N. Diaz, Traian Iliescu, and Youngsoo Choi. Presented in the minisymposium “Generative Models for Scientific Computing: Trustworthiness, Physical Consistency, Computational Challenges, and Applications.”
