Mentoring

I'm looking for highly motivated Ph.D students and Postdocs to join my research group. Interested candicates can send me an email with your CV, research experience, past accomplishments, and a brief description of research ideas you want to pursue. Students with strong background are encouraged to apply for the HK PhD Fellowship Scheme. I may not respond due to the large volume of emails I receive.

Fun

On my free time, I enjoy workout and travel. I shoot street and portrait photography. I love many kinds of authentic food.
