Author IDs


Dr. Denis Yu received his A.B. (Physics) in 1995 from Princeton University and PhD in 2003 (Applied Physics) from Harvard University. After completing his PhD, he moved to Japan to work as an engineer at the Energy R&D Laboratory at SANYO Electric Co. Ltd., developing cathode and anode materials for Li-ion batteries. In mid 2011, he joined the Energy Research Institute at Nanyang Technological University, Singapore, leading the battery and energy storage effort, as well as serving as a co-PI at the TUM CREATE Centre for Electromobility. In June 2013, he joined the City University of Hong Kong as an assistant professor
