Dr Linn Yeh Ching graduated from NUS in 1987 and obtained her MRCP (UK) in 1991.

She has been working in the Dept of Haematology since then and is actively involved in clinical service, research and teaching. Her areas of interest are in haemopoietic stem cell transplantation and cellular immunotherapy.

She has published on various transplant related areas, cytokine-induced killer (CIK) cells and virus-specific T cells. She is principal investigator of clinical studies on use of CIK cells for leukemia post autologous and allogeneic haemopoietic stem cell transplantation in adjuvant and salvage setting, with fundings from National Medical Research Council and SingHealth Research Funds.

She also has a keen interest Traditional Chinese Medicine from the perspectives of evidence – based medicine and its safe use with Western Medicine.
