Enze "Alex" Liu

Computer Security and Privacy Researcher


Hi, my name is Enze (pronounced like the italian name Enzo) Liu. You can also call me "Alex". Right now I am a first-year PhD student in Computer Science at UC San Diego proudly advised by Stefan Savage and Geoffrey Voelker. I am broadly interested in computer security and privacy. My current research focuses on improving cybersecurity with large-scale empirical analyses. Previously, I was fortunate to have done some research on passwords with David Cash and Blase Ur at the University of Chicago.
