Rakesh Kumar is an Associate Professor in the Electrical and Computer Engineering Department at the University of Illinois at Urbana Champaign with research and teaching interests in computer architecture, hardware design, and low power, trustworthy and error resilient computer systems.
He previously served as a Co-Founder and Chief Architect at Hyperion Core, Inc, a microprocessor startup aimed at bringing polymorphous grid processor technology to the market.
He often writes about issues at the intersection of technology, policy, and society -- his opinion columns frequently appear in leading newspapers and magazines.
His research and teaching have been recognized through several best paper awards and best paper award nominations (IEEE MICRO Top Picks, ASPLOS, HPCA, CASES, SELSE, IEEE CAL), Stanley H Pierce Faculty Award, Mahatma Gandhi Pravasi Samman, Ronald W Pratt Faculty Outstanding Teaching Award, ARO Young Investigator Award, Arnold O Beckman Award, and UCSD CSE Best Dissertation Award.
His public service has been recognized by a Nelson Mandela Leadership Award.
Rakesh has a BS from IIT Kharagpur and a PhD from University of California at San Diego.
