In 2025, It has been my 15th career year in the Chinese University of Hong Kong. While I am getting older biologically, according to the life span development theory, I also picked up some new roles socially.

This summer, for example, I collaborated with the Dr Kendrew Mak from the Department of Chemistry to offer a brand new summer course under the Science Academy of Young Talents. Instead of teaching courses on the front line, I stepped a bit backward to serve as a coordinator for the first time; I invited my honourable colleagues to teach the course instead.

The classes were held successfully on 26 and 27 June and I would like to thank Dr Patrick Ngai, Dr Brian Tong, Dr Ryan Yip, and Mr Kelvin Wong for their great effort that I was so proud of.
