Background
I joined DoCoMo USA Labs in October 2007. as a Research Engineer. I received a Dipl. Ing. degree in Electrical Engineering from the University of Belgrade in 1999. In Fall 2000. I joined the University of Maryland at College Park, where I worked as a Graduate Research Assistant at the Institute for Systems Research under the supervision of Prof. John S. Baras. I obtained my M.S. and Ph.D. degrees from the University of Maryland in 2002. and 2007. respectively.
From June - October 2007. I worked as a Research Associate at the Institute for Systems Research at the University of Maryland at College Park.
