Research Interests

Ultrafast real-time optical microscopy and spectroscopy, e.g. fluorescence, Raman; Laser microsurgery for endoscopic applications; novel optical devices for biomedicine; silicon-based photonic devices; optical interconnect.

Dr. Kevin K. Tsia received the B.E. (1st class honor) and M.Phil. degrees in Electronic & Computer Engineering from the Hong Kong University of Science and Technology, Hong Kong, in 2003 and 2005, respectively. He received his Ph.D. degree at the Electrical Engineering Department, at University of California, Los Angeles (UCLA), in 2009. He is currently an Assistant Professor in the Department of Electrical and Electronic Engineering, and the Medical Engineering Program, at the University of Hong Kong.

His research interests covers a broad range of subject matters, including silicon photonics for optical interconnect applications, ultra-fast real-time spectroscopy and microscopy for biomedical applications such as flow cytometry; and endoscopic laser microsurgery. His researches, such as energy harvesting in silicon photonics and the World’s fastest barcode reader and optical imaging system, have attracted worldwide press coverage and featured in many prestigious science and technology review magazines such as MIT Technology Review, EE Times and Science News. Dr. Tsia was the recipient of a fellowship by the California Nanosystems Institute (CNSI) from 2005 to 2006. He also received the 2009 Harry M. Showman Prize from Henry Samueli School of Engineering and Applied Science at UCLA. He is author or coauthor of over 30 journal, conference papers and book chapters. He is also the reviewer for Optics Letters, Journal of the Optical Society of America B, Optics Express, and Applied Optics.
