About

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

Previously, I completed my B.S. in Math and honors Computer Science, and M.S. in Computer Science at Stanford. I was advised by Professors Dan Boneh and John Mitchell during that time.

I organize the Stanford Security Lunch. Please email me to arrange talks!
