Brucek Khailany

Brucek Khailany joined NVIDIA in 2009 and currently leads the ASIC & VLSI Research group.  During his time at NVIDIA, he has contributed to projects within research and product groups on topics spanning computer architecture, unit micro-architecture, and ASIC and VLSI design techniques.  Previously, Dr. Khailany was a Co-Founder and Principal Architect at Stream Processors, Inc. (SPI) where he led research and development activities related to highly-parallel programmable processor architectures. At SPI, he helped lead the development of the industry's first commercially-available stream processor architecture targeting signal and image processing applications. From 1997-2003, at Stanford University, he led the silicon implementation of the Imagine stream processor, a research chip that introduced the concepts of stream processing and efficient partitioned register organizations. He received his Ph.D. and Masters in Electrical Engineering from Stanford University and received B.S.E. degrees in Electrical Engineering and Computer Engineering from the University of Michigan.
