Additional Information:

Professor Qibing Pei joined UCLA in July 2004. He received his Ph.D. in polymer science from the Chinese Academy of Sciences, Beijing. Before joining UCLA Prof. Pei was successively a senior chemist at UNIAX Corporation which was later merged into DuPont Display, and a senior research engineer at SRI International. He has worked on a variety of electro-optic and electro-mechanical devices based on novel polymers he developed, including polymer light emitting diodes, polymer light emitting electrochemical cells, electroactive polymer artificial muscles, and biologically-inspired robots. His research interests cover a wide range of soft materials and span from materials synthesis, processing, to design of functional devices. He applies molecular design and nano-scale engineering in the discovery of new polymers with novel electronic or mechanical property. Prof. Pei also explores new functional devices and integrated systems that may be enabled by the new materials and (nano)structures
