Hi, I’m Ihyun!

I’m a first year Computer Science Ph.D. student at Stanford University, co-advised by Professors David Mazières and Emma Dauterman. My research interests are in applied cryptography and systems security.

Previously, I completed my B.S. in Math and Computer Science (Honors), and M.S. in Computer Science at Stanford. During that time, I had the privilege of being advised by Professors Dan Boneh, David Mazières, and John Mitchell.

Starting in Fall 2026, I’ll be organizing Stanford Security Lunch.
