    Analyzed techniques used by malicious entities, in Twitter, to disseminate dubious information while appearing legitimate. Identified features in their behavior, including their artificially created social network and interaction history, and create algorithms based on these features to distinguish them from regular users.

    PhD, Computer Science
    Georgia Institute of Technology
    Jan 2005 - Jan 2011 (6 years 1 month)
    My graduate work focused on identifying features in communication systems to characterize wanted and unwanted interactions and encapsulate them as interaction credentials. In VoIP, we use call duration and direction to create these interaction credentials and combine them with social network theory and Eigentrust to help distinguish regular users from spammers. We also study how to privately propagate these credentials to address the introduction problem. Currently extending this work to mobile spam.
