Brian Huntly, Professor of Leukaemia Stem Cell Biology at the University of Cambridge, is an internationally renowned leukaemia biologist and clinician-scientist. He has made several seminal contributions to our understanding of the biology and treatment of haematological malignancies. His group made the unexpected observation that malignant lymphomas may initiate in stem and progenitor cells prior to lymphoid commitment. He has a leading national and international role through long involvement with EHA, the NCRI Acute and Chronic Leukaemia groups, editorial boards and international conference organisation. He directs academic clinician-scientist training in Cambridge and his multidisciplinary team provides an outstanding training environment.
