About

I'm a fifth year PhD student in the Department of Computer Science at Cornell University advised by Tom Ristenpart and studying applied security and privacy. My research interests focus on designing secure authentication systems and countermeasures to protect againnst abuse. Most recently, I have worked on detecting password guessing attacks on real login data. In my free time, I can be found singing choral music, singing in operas, and spending time with my husband and son.
