ABOUT ME...


I am a research scientist with background in network security, wireless networks, social network analysis and machine learning. My current interests lie in the areas of cyber security, application of graph databases to fraud detection and security threats and social network analysis.

I received my M.Sc. and Ph.D. from the University of Maryland, College Park, in 2002 and 2007 respectively, and my B.Sc. (5 year degree) from University of Belgrade, Serbia, in Electrical and Computer Engineering in 1999. For a brief period of time after completing my PhD I was a post-doctoral researcher with Institute for Systems Research at University of Maryland.

After completing graduate studies, I joined DOCOMO Innovations in Palo Alto, CA, where I worked on a wide range of projects spanning areas of security, wireless networking, machine learning, social networks, content distribution in mobile networks etc. I am currently with Fair Isaac Corporation (FICO), where I have been a part of the Cyber Analytics team, working on development of a model for detecting a wide range of security threats using a combination of self-learning analytics and anomaly detection techniques. More details HERE (The Wall Street Journal) and HERE. I also worked on applying graph databases for credit card fraud detection.
