Wallace C. H. Choy received his PhD Degree in Electronic Engineering from the University of Surrey, UK in 1999. He then joined National Research Council of Canada as a member of research staff to work on optical device structures of polarization independent optical amplifiers and modulators. He joined Fujitsu at San Jose, US in 2001 to develop real-time wavelength tunable lasers and optical transmitter modules.

He is currently a professor of Department of Electrical and Electronic Engineering, the University of Hong Kong (HKU). Dr. Choy has published over 175 internationally peer-reviewed journal papers, contributed to one book and five book chapters, as well as a number of US and China patents. Among his publications, 12 papers have been featured as cover-story articles such as Adv. Mater., Adv Energy Mater., and Chem Comm., and 14 articles have been highlighted in research new/scholarly articles. Details of publication can be found in He was the recipient of the Sir Edward Youde Memorial Fellowship, the Croucher Foundation Fellowship, and the Outstanding Achievement Award from National Research Council of Canada and HKU Research Output Prize. He received overseas visiting fellowships from HKU to take a sabbatical leave at George Malliaras’s Group, Cornell University in 2008, a visit to Prof. Yang Yang, UCLA in summers of 2009 and 2011, Prof. Karl Leo, Institut fuer Angewandte Photophysik (IAPP), Technische Universitaet Dresden, Germany in the summer of 2010, and Prof./Sir Richard Friend, Cavendish Lab, Cambridge University, UK.

Wallace Choy is a fellow of OSA and senior member of IEEE. He has been recognized as Top 1% of most-cited scientists in Thomson Reuter’s Essential Science Indicators (ESI) three years in a row 2014, 2015 and 2016. He has been recognized as prolific researcher on organic solar cells in the index (WFC in physical sciences) in Nature Index 2014 Hong Kong published by Nature. He has been serving a technical consultant of HK-Ulvac (a member of stock-listed Ulvac Corp) since 2005. He has served as editorial board member for Nature Publishing Group of Scientific Reports and IOP Journal of Physics D, senior editor of IEEE Photonics Journal, topical editor of OSA Journal of the Optical Society of America B (JOSA founded in 1917), and guest editor of OSA Journal of Photonic Research, and Journal of Optical Quantum Electronics. He has delivered over 60 invited talks and served as a committee member in internationally industrial and academic conferences organized by various organizations such as IEEE, OSA and Plastic Electronics Foundation.
