I am an Assistant Professor in the 
Department of Mathematics and Computer Science at Santa Clara University. I received my PhD in Computer Science from Florida State University. I obtained my MSc from Florida State University and my BSc from University of Tehran. My research interests lies in Authentication, Usable security, Information security, Computer and Network security and privacy, and Digital forensics. I have worked on metrics for analyzing password strength and probabilistic techniques for more effective password cracking. I have also worked on search, identification and entity resolution in the Internet.
