Biography

I am a Peter O’Donnell Jr. Postdoctoral Fellow at the Oden Institute at the University of Texas at Austin, and concurrently a Cosmic AI Fellow at the NSF–Simons AI Institute for the Study of Cosmic Origins. I work with Prof. George Biros and Prof. Stella Offner on surrogate modeling of astrochemical networks.

I earned my Ph.D. in Applied Mathematics from the University of Notre Dame under the guidance of Prof. Guosheng Fu. My doctoral research focused on developing high-order variational methods for computing gradient flows and barycenters in generalized Wasserstein spaces. I was co-advised by Prof. Zhiliang Xu.

During my graduate studies, I completed three internships: one at Sandia National Laboratories and two at MathWorks. At Sandia, I worked within the Computer Science Research Institute under Dr. Irina Tezaur and Dr. Anthony Gruber on structure-preserving reduced order models, contributing to the Department of Energy funded M2dt initiative. At MathWorks, I interned with the MATLAB Math & PDE and Simscape Language & Execution teams, where I contributed to the development and enhancement of core features—two of which were included in the release notes of MATLAB R2024a.
