Ph.D. ECE, Georgia Institute of Technology, 2003

Research Interests

Ken Choi joined the Department of Electrical and Computer Engineering at Illinois Tech in the fall of 2007. He was a senior CAD engineer and a technical consultant for ultra-low-power SOC (system-on-chip) design in Samsung and Sequence Design prior to joining Illinois Tech. His research interests include DFP (Design For Power) and DFM (Design for Manufacturing) for ultra-low-power VLSI chip design and automation, and circuit design for nanometer scaled devices such as Carbon Nanotube FETs.
