ZHANG A-ping


Room: CF607



Dr. Zhang received the BSc and MSc degrees from Zhejiang University (ZJU) in 1997 and 2000, respectively, and received his PhD degree from The Hong Kong Polytechnic University in 2003. He started his academic career in ZJU as Lecturer in 2003, and promoted as Associate Professor of Optical Engineering in 2005. He was a Research Scholar of the Institute for Lasers, Photonics, and Biophotonics, State University of New-York at Buffalo during the period of 2006–2008, and the Department of NanoEngineering of University of California, San Diego in 2011, respectively.
He joined the Department of Electrical Engineering of The Hong Kong Polytechnic University as Associate Professor in 2012 and promoted to Professor in 2020.
Dr. Zhang has solid experience in scientific researches and has published more than 100 research papers in international conferences and journals (such as Advanced Materials, Advanced Science, ACS Nano, and Lab on a Chip). His current research interests include: optical micro/nano-manufacturing technologies; photonic devices, sensors, and microsystem; interdisciplinary research and applications. Dr. Zhang was/is the PI of many R&D projects funded by the government and industrial companies. He is the Senior Member of IEEE and OSA.
