Xiangyu is a third-year PhD student at University of Hong Kong. He carries out his research under the supervision of Professor Pengtao Liu. Professor Liu'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.
