Biography
Professor Cao received his B.S. degree in 2004 from Nanjing University, and his Ph.D. in 2009 from the University of Illinois at Urbana-Champaign. After working at IBM Thomas J. Watson Research Center as research scientist for 9 years, he returned to the University of Illinois as an Associate Professor of Materials Science and Engineering, and Affiliate of the Department of Chemistry and of the Department of Electrical Engineering.
Research Interests
Advanced materials for electronics and optoelectronics
Research Description
The Cao group seeks to exploit new materials and processing techniques to develop novel electronic and optoelectronic devices exhibiting enhanced performance and functionality with more custom form factors. This includes high performance extremely-scaled devices for future technology nodes, and low-cost printed electronics for macroelectronics and energy harvesting. These efforts are highly multidisciplinary, requiring a combined expertise in materials science, chemistry, electrical engineering, and device physics.
