I am a Ph.D. candidate in the Department of Computer Science at Princeton University, where I am very fortunate to be advised by Prof. Elad Hazan. Concurrently, I am a research scientist at Google DeepMind. Previously, I completed my undergraduate studies also at Princeton, in the Mathematics Department. I was generously funded by the NSF Graduate Research Fellowship and the Gordon Wu Fellowship from Princeton University.
My research is at the intersection of machine learning, optimization, and dynamical systems. I focus on developing provably robust and efficient methods for sequential decision-making and control, with applications in deep learning and quantum computing.
