Personal Profile

I have 2 PhD degrees (one in astrophysics and one in philosophy). My research focusses on astrophysics, cosmology, philosophy of science, philosophy of religion, dialogue between science and religion, and STEM education. I am elected Fellow of the International Society for Science and Religion, elected Fellow of the Royal Astronomical Society, Expert Adviser (專家顧問) of The Hong Kong Space Museum, and a member of the International Astronomical Union (IAU, 國際天文聯會). I am also a guest host of the RTHK TV talk show 五夜講場—真係好科學 and 五夜講場—學人串社科. In 2022, I received the Humanities and Social Sciences Prestigious Fellowship (人文學及社會科學傑出學者獎) awarded by the University Grants Committee. Currently, I am the Associate Dean (Undergraduate Studies and Student Learning) of the Faculty of Liberal Arts and Social Sciences and the Co-Director of the Christian Faith and Development Centre at The Education University of Hong Kong.
