Welcome!
I am a Ph.D. student in the Statistics Department at the University of Michigan advised by Prof. Ambuj Tewari. Previously, I studied Computer Science and Chemical Engineering also at UM where I worked with Prof. Mahdi Cheraghchi, Dr. Sindhu Kutty, and Prof. Andrej Lenert.
My research interests are broadly anything in Theoretical Machine Learning. Some specific areas of interest include: learning theory, online learning, boosting, bandits, differential privacy, and adversarial robustness.
I am grateful to be supported by the National Science Foundation Graduate Research Fellowship Program (NSF GRFP) from Fall 2022. Feel free to shoot me an email if you’d like me to review your GRFP application! You can find my application materials here.
