Welcome

Our laboratory aims to decode the epigenome to understand how genetic information is read in physiology and diseases. We combine molecular tool development with genetic and genomic approaches to explore epigenetic mechanisms underlying normal physiological functions, and to uncover the epigenetic basis of diseases to accelerate the development of therapeutics. We mainly use human ESC- or iPSC-based system and genetically engineered mouse models to tackle these questions.
