I am a member of the Mobile Solutions Lab (MSL), Samsung Semiconductor, in San Diego, CA.  MSL is engaged in developing solutions in support of next generation 3G and 4G modems and researching core technologies to enhance the competitiveness of Samsung's products.  Prior to joining Samsung, I was an Assistant Professor at Virginia Tech, where my research was mainly focused on dynamic spectrum access and cognitive radio networks.  While with Virginia Tech, I also conducted research in the areas of millimeter-wave (60 GHz) system design, source localization, interference cancellation, and network scalability analysis.  I spent the summer of 2004 with the Corporate Technology Group of Intel Corp.

I received the B.S. and M.S. from the State University of Campinas, Brazil, in 1999 and 2001, respectively, and the Ph.D. from the University of California, San Diego in 2005, all in electrical engineering.  I received the best student paper award at the 2003 IEEE Conference on Ultra-Wide Band Systems and Technologies, and was a California Institute of Telecommunications and Information Technology (Calit2) graduate student fellow for the 2001-2002 academic year.  In 2013, I received an IEEE Wireless Communications Letters exemplary reviewer award.

I'm an Associate Editor for Modulation and Signal Design for the IEEE Transactions on Communications and have served on the technical program committee of numerous IEEE conferences in the communications area.  I am a senior member of the IEEE.
