David Ho

David Da-i Ho (; 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.

Early life and education Ho was born in Taichung, Taiwan, on November 3, 1952, the eldest of two sons. His mother, Sonia Chiang Shuang-ju , was a native of Taichung. His father, Ho Pu-chi (; 1919–2009), was a native of Shangli, Jiangxi, who graduated from Zhejiang University and moved from mainland China to Taiwan in 1947 to work as a teacher at Changhua Girls' Senior High School. Pu-chi was a devout Christian who took the Christian name Paul, The family's ancestral home was in Xinyu, Jiangxi. According to Time, "the Ho family lived in a modest four-room house with a backyard ditch that served as a toilet and from which farmers collected fertilizer for their fields". He was raised in Los Angeles and, after attending John Marshall High School, graduated from the California Institute of Technology with a Bachelor of Science (B.S.) in biology with highest honors in 1974. As an undergraduate, he worked at a lab at MIT under immunologist Herman Eisen. He then earned his Doctor of Medicine (M.D.) from Harvard Medical School in 1978. and other early 1990s antiretroviral medication were prescribed in single therapy, which still did not prevent progression to fatal full-blown AIDS. In the mid-1990s, his research team conducted a series of elegant human studies to elucidate the dynamics of HIV replication in vivo. which had been subsequently developed by scientists at NIAID and Merck. He and his ADARC team presented the remarkable results from using combination antiretroviral therapy at International AIDS Conference 1996. This was the turning point in the epidemic that an automatic death sentence was transformed into a manageable disease.

Ho is a member of the Committee of 100, a Chinese American leadership organization, in addition to several scientific groups.

Ho led a team, funded by the Jack Ma Foundation, to look for a vaccine for the COVID-19 virus.

Honors and titles Ho was Time magazine's 1996 Man of the Year. Time later recalled the selection surprising both Ho and readers. The magazine acknowledged in 1996 that "Ho is not, to be sure, a household name. But some people make headlines while others make history." Ho was even briefly mentioned when Alexander Fleming was considered for Person of the Century in 1999, since Fleming could be portrayed as representative of other disease-fighting scientists including Ho, but the title ultimately went to Albert Einstein.

Ho was the chosen commencement speaker at Caltech, MIT, and Harvard T. H. Chan School of Public Health in 2000.

Ho has received numerous honors and awards for his scientific accomplishments. On January 8, 2001, he was presented with the Presidential Citizens Medal by President Clinton.
