Chi On Chui, Ph.D.

ChuiAssociate Professor of Electrical Engineering and Bioengineering, and Member of California NanoSystems Institute (CNSI), University of California, Los Angeles (UCLA), CA, USA Co-Founder of Selfa, Inc., Los Angeles, CA, USA

Professor Chui received his B.Eng. degree from Hong Kong University of Science and Technology (HKUST) and his M.S. and Ph.D. degrees from Stanford University. He joined Intel Corporation as a Senior Device Engineer after his Ph.D. in 2004 and also served as a Researcher-in-Residence at UC Berkeley and Stanford. He was also appointed Consulting Assistant Professor at Stanford at the same time. He joined the UCLA faculty in 2007 and is currently an Associate Professor of Electrical Engineering and Bioengineering, and a member of the California NanoSystems Institute. In 2013, he co-founded Selfa, Inc.

The Chui Laboratory at UCLA conducts research on label-free technologies for ultrasensitive and transient biomolecular quantification and cellular phenotyping. One major invention in his laboratory in the past 5 years is the semiconductor electronic label-free assay (SELFA) platform, which is based on a novel amplifying transistor biosensor technology that performs electronic detection and amplification of biomolecular binding events with outstanding sensitivity and specificity. Using SELFA, his laboratory has demonstrated biomarker quantitation in clinical specimens, such as plasma and urine, with 100-1000 times lower limit of detection compared to the gold standards. His laboratory actively collaborates with cardiologists, nephrologists, infectious disease experts, toxicologists, gastroenterologists, neuroscientists and others to further validate and explore potential applications of the SELFA platform. Another recent breakthrough in his laboratory is a very high-throughput single-cell manipulation platform directly operable in physiological media.

Professor Chui has published about 130 peer-reviewed and invited archival journal and conference publications, 6 book chapters, and 9 issued patents. He has reviewed domestic and overseas research grant applications and scientific paper manuscripts, served as a technical expert witness on patent infringement litigation, and consulted for domestic and overseas medical device companies and semiconductor foundries. He has received several recognitions for his work including 3 best paper awards and 3 poster prizes. Most notably, he is the 1st recipient of the IEEE Electron Device Society Early Career Award in 2009, which is regarded as one of the Society’s highest honors. He also received the Chinese American Faculty Association (CAFA) Robert T. Poe Faculty Development Award, the UCLA Faculty Career Development Award, and the UCSD von Liebig Entrepreneurism Center Regional Health Care Innovation Challenge Award. Most importantly, he received the UCLA Henry Samueli School of Engineering and Applied Science Northrop Grumman Excellence in Teaching Award.
