I am a research scientist at Sprint Applied Research & Advanced Technology Labs (ATL), California. I received Ph.D. in Computer Science and Engineering at the Pennsylvania State University. During my Ph.D. study, I had worked on security and privacy issues in three types of wireless networks: cellular networks, mobile ad hoc networks, and sensor networks. I focused on designing algorithms and systems research. My Ph.D. advisor is Dr. Thomas F. La Porta who is the director of Networking and Security Research Center at the Penn. State University. Currently, I am working on WiMAX vulnerability assesment and misbehavior detection and mitigation project at Sprint.
