About me

Hello! I am a 5th-year Electrical and Systems Engineering PhD student in the GRASP lab at the University of Pennsylvania. I am fortunate to be advised by Prof. Nikolai Matni. Previously, I graduated with BSc degrees in Mathematics and in Statistics & Data Science from Yale University. I then spent a year as a researcher in the Kluger Lab at Yale University's Applied Mathematics Program. During the summer of 2023, I interned at Microsoft Research NYC.

I am interested in:
