Dr. Yifei Li received his B.Eng. in Optoelectronics from Huazhong University of Science and Technology, China, in 1996. He received his MS (2001) and PhD (2003) in Electrical Engineering both from Drexel University, Philadelphia, PA. From 2003 to 2007, he was a research faculty with the Center for Microwave-Lightwave Engineering, Drexel University. In 2007, he joined the ECE Department of the University of Massachusetts Dartmouth, where he is currently a full professor and the director of the RF Photonics Lab. From 2013 to 2014, Dr. Li was a visiting faculty in the Optoelectronic Research Group of the University of California Santa Barbara. Dr. Li’s research interests includes RF photonics, photonic integrated circuits, coherent optical communications, RF devices and systems, and laser physics.

Dr. Li has five US patents in RF Photonics. He has numerous publications in renowned technical journals and international conference proceedings. Since he joined UMassD, he has led 8 competitive research projects funded from the Navy, Airforce and DARPA as the Principle investigator. Dr. Li was a winner of European Microwave Association (EuMA) Young Scientist Prize (1st prize) during the 12th Colloquium on Microwave Communications held in Budapest, Hungary. He was a winner of 2008 DARPA MTO Young Faculty Award.
