Prof. Sham Mai-har (岑美霞) joined the Chinese University of Hong Kong in 2020. She is currently Choh-Ming Li Professor of Biomedical Sciences. Professor Sham did her undergraduate and MPhil studies in the Chinese University of Hong Kong. She obtained a Croucher Foundation Scholarship and pursued her PhD in Biochemistry in the University of Cambridge. She received her postdoctoral training in Developmental Genetics in the National Institute for Medical Research in London, U.K., before joining the University of Hong Kong. She had previously served as the Associate Vice-President (Research), Head of the Department of Biochemistry, Assistant Dean (Research), Director of the Centre for Reproduction Development and Growth in the Li Ka Shing Faculty of Medicine, the University of Hong Kong.
Professor Sham’s research focused on the molecular mechanisms of mammalian development and human congenital disorders. Her research group works on transcriptional regulation and functional genomics in craniofacial and sensory neural development and diseases. Her research laboratory uses mutant mice, stem cells and organoids, and single-cell technologies as experimental platforms. Current projects include:
- Irx genes and their transcriptional regulations in inner ear development and hearing disorders
- Sonic hedgehog signaling genes in sensory and non-sensory cochlear epithelium development
- Notch signaling and transcriptional regulations in cranial placode, neural crest and craniofacial development
- The role of Sox10 and Eph/ephrins in enteric nervous system development
