Biography

 

Dr. Chan has been the Scientific Officer of our department since 2006. She also serves as the Safety Officer of our laboratories and oversees the daily operation of the laboratory. 

She has immense interest in conducting research in neonatology and paediatric oncology, including the pathophysiology of necrotising enterocolitis, developmental immaturity in innate immune responses and haematological malignancies. She is currently developing rapid tests for detecting bacterial infections, gastrointestinal conditions and drug-induced tissue damage in paediatric patients.  

Dr. Chan obtained her first degree in biotechnology and PhD degree in Molecular Biology from the University of Hong Kong. She then pursued her postdoctoral training in the Department of Clinical Oncology and, Anatomical and Cellular Pathology in the Chinese University of Hong Kong. She received technical training on genomics, transcriptomic and network analysis at the National Institutes of Health (USA) as a visiting scientist in 2008.
