About Me

I will be on the faculty job market in Fall 2024. Stay tuned for my job application materials!

Hi, my name is Enze (pronounced like the italian name Enzo) Liu. I also go by the English name "Alex". I am a fifth-year PhD student in Computer Science at UC San Diego, where I am proud to be advised by Stefan Savage and Geoff Voelker. I am broadly interested in understanding, modeling and mitigating real-world cybercrime and abuses. My current research investigates cryptocurrency-related scams and hacks, and I researched email security (WWW 24, SOUPS 23, EuroS&P 23 , IMC 21) and Android stalkerware (PETS 23, IMC 20 ) in the past. In my spare time, I worked on several side projects, with topics ranging from remote memory (WORDS 23) to DNS hijacking (IMC 21) to reducing selective exposure (CSCW 24). Before starting my PhD, I spearheaded some research on passwords (S&P 19) working with David Cash and Blase Ur at the University of Chicago.

When not squashing bugs or hacking a server, I enjoy swimming, rock climbing, walking around the city (ideally, with friends), playing tennis/table tennis and hunting for great food. Occasionally, you can find me surfing at various beaches in San Diego or camping in the middle of nowhere. My hometown is Wuhan, China.
