About Me

I am a fourth-year PhD student in the Computer Science department at University of Chicago. I am advised by Prof. Heather Zheng and Prof. Ben Zhao. My research focuses on security and privacy in machine learning. I received my bachelor’s degrees in Computer Science and Mathematical Sciences with a minor in Computational Finance from Carnegie Mellon University in 2020. I received my master’s degree in Computer Science – Research Thesis from Carnegie Mellon University in 2021, jointly advised by Prof. Nihar Shah and Prof. Weina Wang.
