Saranga received his PhD degree in Societal Computing from Carnegie Mellon University. His research focus was usable security: the design of secure systems with a human-centric approach. Saranga's doctoral research on estimating password strength using machine learning contributed to the revision of NIST's guidelines for secure passwords, which influence the password policies of thousands of organizations.
Saranga's research interests also include privacy, online advertising, and social networks. He has published and spoken at top academic conferences such as the IEEE Symposium on Security and Privacy, the ACM Conference on Computer and Communications Security, the Symposium on Usable Privacy and Security, and USENIX Security, among others.
Saranga is currently principal software architect at a start-up company, with expertise in security engineering, site reliability, cloud applications, and data science. He lives in the Pacific Northwest with his wife and two young boys.
