David Ho

David Da-i Ho (Chinese: 何大一; pinyin: Hé Dà-yī; born November 3, 1952) is a Taiwanese-American physician-scientist and virologist known for his contributions to HIV/AIDS research. He pioneered the use of combination anti-retroviral therapy instead of single therapy in the treatment of HIV infection which transformed HIV from an absolute terminal disease into a chronic disease. Ho was born in Taiwan in 1952 and immigrated to the United States in 1965. After graduating from the California Institute of Technology, he earned his Doctor of Medicine (M.D.) from Harvard Medical School, then received his clinical training at the UCLA School of Medicine and Massachusetts General Hospital. He is the founding scientific director of the Aaron Diamond AIDS Research Center and the Clyde and Helen Wu Professor of Medicine at Columbia University Vagelos College of Physicians and Surgeons, both housed at Columbia University Irving Medical Center.
