I am an assistant professor in the department of computer science at Columbia University. My primary research interests are at the intersection of computer security and machine learning. More specifically, I am interested both in using machine learning to improve software security and in improving security and reliability of the machine learning models themselves. I also occasionally delve into software engineering and operating systems.
