Research expertise: Circuits and architectures for low power and high performance VLSI for harsh environments, CAD for VLSI

Lawrence T. Clark worked at Intel Corporation after receiving his bachelor’s degree in computer science in 1983. While completing doctoral studies he worked at VLSI Technology Inc. designing PC chipsets. He received his Ph.D. in 1992 after receiving his M.S. in 1987, both in electrical engineering from Arizona State University. He re-joined Intel in 1992. Clark joined ASU in August 2004. Professor Clark has been awarded over 115 patents with approximately 10 pending. He has published more than 130 peer-reviewed technical papers and nine book chapter. He has about 20 years of industry experience in various aspects of VLSI, CMOS imager, microprocessor design, test engineering, as well as TCAD compact modeling. At Intel he contributed to the Pentium, Itanium and XScale microprocessor designs. Most recently, he was a principal engineer and circuit design manager for the Intel XScale microprocessor designs. He also worked with SuVolta Inc. from 2009-2014, where he was chief architect.
