I am an Neubauer Family Assistant Professor at the Department of Computer Science, University of Chicago. I received my PhD at Department of Computer Science, Columbia University. I am broadly interested in Security, Software Engineering, and Machine Learning, focusing on developing data-driven program analysis to improve the security and reliability of both traditional and AI-based software systems. I get most excited about developing machine learning models that can reason about program structure and behavior to precisely and efficiently analyze, detect, and fix software bugs and vulnerabilities.
