I am a graduate of Medical Engineering as my first degree and Doctor of Philosophy in Mechanical Engineering from The University of Hong Kong. I have been working on biophotonics research experience of 10 years. The overall research direction is on ultrafast single cell imaging making use of laser time-stretch technology. With the imaging methodology, both brightfield and quantitative phase image of the flowing cell could be reconstructed. This enables the possibility of ultra high speed imaging flow cytometry utilizing this method, with no necessity of staining the cell sample for interrogation. In order to match up with market available cytometers' functionality, sorting mechanism should also be embedded to the ultrafast flow cytometry. Currently I am working on microfluidic cell sorting mechanism to cope with the speed and accuracy that brought by the imaging flow cytometry.
