Dr. Pui’s work helped push the cure rate of acute lymphoblastic leukemia, the most common childhood cancer, above 90% and improved the quality of life of survivors. He has formed two national and international study groups and organized major annual national and international teaching conferences to promote research and extend the curative treatment globally. He has published over 1000 articles and is one of the most highly cited researchers. For his significant contributions to the field of pediatric oncology, he has been honored with many prestigious awards, professorships and degree including elected fellow of American Association for the Advancement of Science, and membership to the American Society of Clinical Investigation, Association of American Physicians, Academia Sinica (Taiwan) and Chinese Academy of Engineering.
