Ho Yin Chan, Edwin holds B.Sc. degree in biochemistry from CUHK, and completed his PhD in genetics at University of Cambridge with Cahir J. O’Kane. Edwin’s graduate work focused on the genetic study of a RNA-binding protein gene in dribble, and discovered its role in regulating pre-ribosomal RNA processing. He received postdoctoral training at University of Pennsylvania. Since 1999, Edwin investigates pathogenic pathways of repeat expansion diseases, including spinocerebellar ataxias, Huntington’s Disease, amyotrophic lateral sclerosis and myotonic dystrophy, which belong to a group of rare neurodegenerative and neuromuscular diseases. In 2002. Edwin established his research program at CUHK. His group takes a multi-disciplinary approach to identity new disease loci, study disease pathogeneses, and develop therapeutics for these disorders. In 2012, his group reported the role of nucleolar stress in repeat expansion diseases. This finding opened up a new window for novel therapeutic development. In terms of technology transfer, Edwin currently holds 6 US patents. He co-founded his company Rare Power Limited in 2023. In 2024, Rare Power Limited was admitted to the Hong Kong Science and Technology Parks’ IncuBio Programme.
