Biography

I am a Junior Research Fellow in Physics at St John’s College, Oxford. My research interests center around the practical implementations and applications of the noisy quantum computers that we will soon have.

I grew up in Shantou, a small coastal city in China renowned for its great food (and thus my passion for cooking). I finished my secondary education in Singapore before I went to Cambridge for my undergrad and subsequently Oxford for my PhD under the supervision of Simon Benjamin.
