I am a Ph.D. student under the supervision of Prof. Augustin Chaintreau in Computer Science at Columbia University. My research interests are in social networking, machine learning, and graph neural networks. Prior to Columbia, I received my M.S. degree in Statistics at Stanford University.

I obtained my B.S degree at the the Johns Hopkins University, where I worked with Prof. Edward Scheinerman on discrete mathematics, and I triple-majored in Applied Mathematics and Statistics, Computer Science, and Mathematics.
