Saba Eskandarian Office: 346 Brooks Building Email: saba@cs.unc.edu I am an assistant professor in the Department of Computer Science at the University of North Carolina at Chapel Hill. My research focuses on applied cryptography, security, and privacy. Previously, I was a PhD student in the Applied Cryptography Group at Stanford University, advised by Dan Boneh. Before that, I completed my bachelor's and master's degrees in Computer Science with an undergraduate minor in Applied Mathematics at the University of Virginia, advised by Mohammad Mahmoody. I made a tool for more easily viewing UNC course listings. I am looking for new PhD students for fall 2025! Please see the UNC CS admissions page for information about applying.
