BIOGRAPHY:

Kevin Tsia received his Ph.D. degree at the Electrical Engineering Department, at University of California, Los Angeles (UCLA), in 2009. He is currently an Associate Professor in the Department of Electrical and Electronic Engineering, and the Medical Engineering Programme, at the University of Hong Kong. His research interest covers a broad range of subject matters, including ultra-fast real-time spectroscopy and microscopy for biomedical applications such as imaging flow cytometry, MHz optical coherence tomography. His pervious 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 received Early Career Award 2012-2013 by the Research Grants Council (RGC) in Hong Kong. He received the Outstanding Young Research Award 2015 at HKU. His recent research on ultrafast optofluidic imaging technology, dubbed “ATOM”, has also been covered by local media and scientific magazines. He is author or coauthor of over 120 journal, conference papers and book chapters. He holds 2 granted and 2 pending US patents on ultrafast optical imaging technologies.
