David Ho

David Da-i Ho (born November 3, 1952) is a Taiwanese American AIDS researcher, physician, and virologist who has made a number of scientific contributions to the understanding and treatment of HIV infection.

He championed for combination anti-retroviral therapy instead of single therapy, which turned HIV from absolute terminal disease into a chronic disease.

David Ho was born in Taiwan in 1952 and immigrated to the United States in 1965, where he was educated at California Institute of Technology and Harvard Medical School (through the Harvard–MIT Program in Health Sciences and Technology) before getting his clinical training at 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.

David Ho was born in Taichung, Taiwan, to Paul, an engineer, and Sonia Ho (née Jiang).

David Ho attended Taichung Municipal Guang-Fu Elementary School until sixth grade before immigrating to the United States with his mother and younger brother to unite with his father, who had already been in the US since 1957.

He grew up in Los Angeles and graduated from John Marshall High School.

He received his Bachelor of Science in biology with highest honors from the California Institute of Technology (1974).

Ho has been engaged in HIV/AIDS research since the beginning of the pandemic, initially focusing on clinical virology and select topics in HIV pathogenesis, including HIV drug resistance.

In the mid 1990s, his research team conducted a series of elegant human studies to elucidate the dynamics of HIV replication in vivo. This knowledge, in turn, formed the foundation for their pioneering effort to treat HIV "early and hard" and in demonstrating for the first time the durable control of HIV replication in patients receiving combination antiretroviral therapy, which had subsequently developed by scientists at NIAID and Merck.

Before 1996, AZT and other early 1990s antiretroviral medication were prescribed in single therapy, which still did not prevent progression to fatal full-blown AIDS.

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 was Time magazine's 1996 Man of the Year.

Time later recalled the selection surprised 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."

In 1998, he received the Golden Plate Award of the American Academy of Achievement.

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.

On December 6, 2006, California governor Arnold Schwarzenegger and First Lady Maria Shriver inducted Ho into the California Hall of Fame located at The California Museum for History, Women, and the Arts.

Ho was awarded the Distinguished Alumni Award by California Institute of Technology in 2015.

Ho received the Portrait of a Nation Prize at the National Portrait Gallery, Smithsonian Institution in 2017.

Other accolades include the Ernst Jung Prize in Medicine, Mayor's Award for Excellence in Science & Technology, the Squibb Award, the Architect of Peace and the Hoechst Marion Roussel Award.

Ho has been elected as a member of the American Academy of Arts and Sciences, Academia Sinica (Taiwan), and the U.S. National Academy of Medicine (formerly Institute of Medicine).

He is currently a member of the board of trustees of the California Institute of Technology.

He was a member of the Board of Overseers of Harvard University and a board member of the MIT Corporation.

He is the recipient of 14 honorary doctorates, including those from Columbia University and Tsinghua University.

He is also a member of the Chinese Academy of Engineering.

Ho is an honorary professor at Peking Union Medical College, Chinese Academy of Medical Sciences, Chinese Academy of Sciences, University of Hong Kong, Wuhan University, and Fudan University in China.

Ho was recognized by the Kingdom of Thailand with the Prince Mahidol Award in Medicine.

Ho was awarded Hamdan Award for Medical Research Excellence - Immunity in 2022.

His family's ancestral home is Xinyu, Jiangxi Province.

Ho has published more than 500 research papers as of February 2020.

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 Jack Ma Foundation, to look for a vaccine for the COVID-19 virus.

Ho believes that other treatments that may become effective against COVID-19 should be examined.

As of 2020, Ho is the last person to be selected as Person of the Year in a U.S. presidential election year without winning that year's U.S. presidential election.
