About Me

I am a third-year PhD student in Machine Learning at the Georgia Institute of Technology advised by Vidya Muthukumar and Jacob Abernethy. I completed my BS in Applied and Computational Mathematics at the University of Southern California advised by Shaddin Dughmi, where I was a Trustee Scholar and Viterbi Fellow. My work is generously supported by the DoD NDSEG Fellowship.

I am interested in advancing our scientific understanding of deep learning using both theory and experimentation. My current focus is characterizing the generalization phenomena of overparameterized neural networks and developing provable algorithms for robust learning, particularly under distribution shift. I also work on applying mathematically-justified techniques to large-scale language and vision models. The ultimate goal of my research is to enable the safe and trusted deployment of deep learning systems in high-consequence applications such as medicine, defense, and energy.
