Margaret H.L. NG(吳香玲)


Personal Profile:

Professor Margaret NG is a haematopathology specialist, who has worked in the Department of Anatomical & Cellular Pathology, Prince of Wales Hospital as a member of the Faculty of Medicine, The Chinese University of Hong Kong since 1988. As a graduate from the CUHK, she is one of the few who joined her alma mater shortly after graduation and has been staying there to contribute for 3 decades till now, as Professor and Director in Haematopathology Section and the Honorary Chief of Service for the Hospital Authority.

Never dreamt to be a pathologist. As a student, she found pathology as an extremely hard subject. Unlike other graduates, her career path after graduation is totally not straight forward as the first batch of CUHK medical graduates in those days despite a rather attractive academic record [Gold Medal in Medicine and The most Outstanding Medical Student 1986]. Haematopathology was not a prominent specialty then, and to most people almost non-existent. Given the chance to work in the Dept. of A & C Pathology (Department of Morbid Anatomy then) by the then founding chairman, Prof. CK Lee, she chose to start training in haematopathology, based on just one reason. She liked the teaching on haematology given by the academic paediatric team and her dissertation in paediatric clerkship was on immune/idiopathic thrombocytopenic purpura, for which she was awarded a Cow & Gate Price in Perinatology. That was so encouraging to young Margaret.

Correct or not, her choice brought her to a field with diversified nature of service operations. She always describes haematopathology as a pathology cocktail, with automated analyzers dealing with a lot of numerical data like chemical pathology, with morphology assessment on glass slides like cyto/histo-pathology, with cell culture for chromosomes and stem cells in biological studies like microbiology and with provision of stem cell and blood products like a pharmacy. As a small specialty, not many informed experiences from seniors in the field for references that could be exploited to fine steer one’s perspectives. It has been a total adventurous expedition

Margaret obtained MRCPath (UK) in 1993 and became FRCPath (UK) in 2002. FHKCPath and FHKAM(Path) were awarded in 1994 and 1995 respectively. In the course of Fellowship training, she was thankful to a few teachers in Hong Kong, Dr. C S Feng, the late Prof. David Todd, Prof. TK Chan, Dr. Albert Lei, Dr. Edmond Chui and in Oxford, Dr. Pauline Emmerson, Dr. Tim Littlewood, Dr. James S Wainscoat and Dr. Paul Giangrande, where in the latter she spent over 6 months learning in the clinics, wards, laboratory, transfusion center and haemophilia center. Both the local and overseas training have critically benefited her in her professional developments. Out of curiosity and thinking of equipping herself with better managerial skills, she started on a part time MBA program in 1991 and obtained MBA (Warrick, UK) in 1996.

She obtained her MD, CUHK in 2003 based on the theme-based research on cytogenetics and epigenetics on Chinese myeloma that led to the publication of a series of papers in British Journal of Haematology, Clinical Cancer Research, American Journal of Pathology, Human Pathology, Apoptosis, Leukemia & Lymphoma and Oncology Reports.
