Professor LEUNG Kam Tong

  • Assistant Professor, Department of Paediatrics

BSc (Biology), MPhil (Biology), PhD (Medical Sciences)


Dr. KT Leung received his PhD degree and postdoctoral training from the Department of Paediatrics, The Chinese University of Hong Kong, and thereafter commenced his academic career in the same unit. He is currently leading a young but ambitious Paediatric Haematology/Oncology Research Team under the Hong Kong Hub of Paediatric Excellence (HK-HOPE) in the Hong Kong Children’s Hospital, comprising 18 members of scientific officer, postdoctoral fellows, postgraduate students, laboratory technicians and research assistants.

He is a dedicated haematologist with ample expertise in blood diseases. His research portfolio spans basic, translational and clinical hematology, with a particular focus on childhood leukemia and haematopoietic stem cell transplantation. He has published 50+ papers in leading journals in the field of hematology, including Blood, Blood Cancer Discovery, Blood Advances, Leukemia and Haematologica, and has obtained 21 research grants in the capacity of principal investigator with a total sum of HKD 36.8M, including external competitive RGC, HMRF and ITF fundings from the Hong Kong SAR Government. With decade-long efforts, he has collected 1000+ bone marrow specimens from children with leukemia, consolidating a unique specialty and an area of research excellence in Hong Kong.

Dr. Leung’s research has also reached national and international scale, as exemplified by his collaborative studies with world-renowned centers in China, Europe and USA. He has received the Young Investigator Award from the International Society of Paediatric Oncology and is an active member of the American Society of Hematology and European Hematology Association. Beyond the academia, he is also well-connected with industrial partners to co-develop and commercialize the next-generation therapeutics for blood cancers and currently serving the Hospital Authority and Department of Health for reviewing research ethics and manufacturers licensing of advanced therapy products.
