I recently (April 2009) completed my Ph.D. in the COS (Computation, Organizations and Society) program with the School of Computer Science at Carnegie Mellon University. My research interests include information security, cyber crime, trust, human computer interaction, security and privacy issues related to technologies that can improve quality of life, and learning science.

I am currently working on a National Science Foundation (NSF) funded project, Supporting Trust Decisions with Dr. Alessandro Acquisti, Dr. Lorrie Cranor (Advisor) and Dr. Jason Hong. My current research aims at modeling trust behavior of users while using the Internet and to make use of the model to build a training system called PhishGuru. I am also involved in developing an online game Anti-Phishing Phil.

Prior to the current research, I was working on understanding privacy attitudes and awareness in India. I conducted a survey in India among students, professionals, researchers and professors during Spring 2004. The analysis of the data showed some interesting results. The research papers published in this area can be found in publications.

I am a member of CMU Usable Privacy and Security Laboratory CUPS.

My anti-phishing research work at Carnegie Mellon University has contributed in creating a start-up company, Wombat Security Technologies.
