My primary interests include cognitive radio, wireless networks, and security. Most of my current research involves advancing the state of the art in Software-Defined Radio (SDR) and Cognitive Radio (CR). I hold a number of positions within the IETF, working to standardize secure protocols for wireless networks.

I received my Ph.D. from the University of Maryland in Computer Science, where my advisor was Bill Arbaugh. My dissertation research was an information-theoretic analysis of the FCC's Interference Temperature proposal for dynamic spectrum access. While at the University of Illinois, I received my MSEE while working with Dick Blahut on information-theoretic cryptography.

In my role at LTS, I'm managing and participating in a variety of research collaborations:

• University of Maryland: several cognitive radio projects looking at fading channels, interference, and spectrum access
• Virginia Tech: continued development of open-source SCA implementation, OSSIE
• University of Texas: developing middleware for wireless, delay-tolerant networks
• GNU Radio: engine enhancements to support real-time implementations of digitial waveforms on the IBM Cell Broadband Engine

As an adjunct professor, I can advise Undergraduate and Masters students in the Electrical and Computer Engineering department, and serve on and co-direct Ph.D. dissertation committees. If you have been admitted to the ECE department at UMD and are interested in working with me, please email me. Realize that I am not a full-time faculty member, and consequently can only accept a limited number of students. Also, I don't have any funding available to support research assistants.
