Research Scope


An overview of research focus

Our team, comprises of renowned paediatric oncologists, haematologists and pathologists, has a long-standing research interest in clinical and translational haematology, and is dedicated to develop new treatment modalities for children suffering from leukemia. The research site is located at the Hong Kong Children’s Hospital where all childhood leukemia cases are now being centralized for management.


A list of research topics

  • Clinical trials for childhood leukemia

  • Leukemia immunology and chimeric antigen receptor T cells

  • Therapeutic antibodies and small-molecule inhibitors

  • Functional genomics and precision medicine

  • Single-cell transcriptomics and high-dimensional analyses

  • Molecular mechanisms of hematopoietic stem cell transplantation
