Research Interests

In 1999, Wallace Choy 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 an associate professor of Department of Electrical and Electronic Engineering, the University of Hong Kong (HKU). His current research interests are concerned with organic optoelectronic devices, plasmonic structures and nano-material devices, and optical and electrical properties of organics, metal nanomaterials and metal oxides. Dr. Choy has published over 135 internationally peer-reviewed journal papers, contributed to one book and five book chapters, as well as a number of US and China patents. 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. Y. 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 for studying organic LEDs and solar cells.

Wallace Choy is recognized as the Top 1% Scientists in the field of Materials Science based on Thomson Reuter's Essential Science Indicators (ESI) in 2014. He has been serving a technical consultant of HK-Ulvac (a member of stock-listed Ulvac Corp) since 2005.  He has served as associateeditor/ guest editor/ member of editor board of a number journals such as IEEE Photonic Journals, OSA Journal of Photonic Research, Journal of Optical Quantum Electronics on Numerical Simulation of Optoelectronic Devices and International Journal of Optics. He has delivered a number of 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. He is now a senior member of IEEE.
