Hi! I am a Lecturer at the Innovation Academy, Faculty of Engineering, HKU. I received my PhD degree from the University of Hong Kong under the supervision of Prof. Ben Kao. My research interests include knowledge-based systems, information extraction and legal technology applications.

I organize and lead out-of-classroom engineering learning activities. Opportunities for collaboration are welcomed, so please feel free to reach out!
