Nikola Nedovic

Nikola Nedovic joined NVIDIA Research in 2016. He received a Dipl.Ing. degree in electrical engineering from the University of Belgrade, Serbia, in 1998 and the Ph.D. degree from the University of California at Davis, in 2003. Before joining NVIDIA, he was a senior researcher and research manager at Fujitsu Laboratories of America, Inc., Sunnyvale, CA, where he worked on circuits and systems for electrical and optical communications, and energy-efficient VLSI implementations of machine learning computing systems. His research interests include high-speed analog and mixed-signal circuits for wireline communications, design and modeling of large mixed signal systems, adaptation and learning algorithms, and circuit design and clocking strategies for high-performance and low-power digital applications.
