Xiangyu is a third-year PhD student at the School of Biomedical Sciences of the University of Hong Kong. He carries out his research under the supervision of Professor Pengtao Liu. Professor Lui's lab has a multidisciplinary focus spanning developmental biology, ageing mechanisms, and host-virus interactions, utilising expanded potential stem cells (EPSCs) as a versatile experimental platform. Xiangyu's doctoral work specifically investigates the molecular functions of METTL3, the major RNA m⁶A methyltransferase, during critical stages of early human development. His research aims to decipher how m⁶A modifications regulate cell fate decisions in pluripotency maintenance and trophectoderm specification, providing mechanistic insights into epigenetic control of embryogenesis.
