Biography

Dejan Markovic received the Dipl.Ing. degree from the University of Belgrade, Serbia, in 1998 and the M.S. and Ph.D. (thesis) degrees from the University of California, Berkeley, in 2000 and 2006, respectively, all in Electrical Engineering. In 2006, he joined the faculty of the Electrical Engineering Department at the University of California, Los Angeles as an Assistant Professor. His current research is focused on digital integrated circuits and architectures for parallel data processing in wireless communications and neuroscience, including optimization methods and supporting CAD flows. Dr. Marković was awarded the CalVIEW Fellow Award in 2001 and 2002 for excellence in teaching and mentoring of industry engineers through the UC Berkeley distance learning program. In 2004, he was a co-recipient of the Best Paper Award at the IEEE International Symposium on Quality Electronic Design. He received 2007 David J. Sakrison Memorial Prize from the Department of EECS, UC Berkeley.
