Hi! I'm a third-year undergraduate at the Georgia Institute of Technology studying Mathematics. I am fortunate to work with Prof. Yongxin Chen and Prof. Amirali Aghazadeh on the mathematical foundations of machine learning. Outside of research, I enjoy photography, writing, reading, and bouldering. This past summer I participated in a REU at Williams College; next summer I'll be a Quantitative Trading Intern at Susquehanna International Group (SIG).

Research

My research centers on reasoning about machine learning from mathematical first principles, with a particular focus on high-dimensional probability and geometric deep learning. Previously, I have worked on structure-preserving generative models, including diffusion on Riemannian manifolds, normalizing flows, and sampling acceleration for discrete processes.

Currently, I am working on convergence bounds for Sequential Monte Carlo. Recently, I also worked on Geometric Flow Matching and Martingale Optimal Transport.

I am also interested in differential geometry, natural language processing, and algorithmic alignment.

Academics

I have taken a fair amount of undergraduate and graduate courses in mathematics and computer science. Here are some highlights, with * indicating graduate courses.
