Hwang Woo-suk (Korean: 황우석, born January 29, 1953) is a South Korean veterinarian and researcher. He was a professor of theriogenology and biotechnology at Seoul National University (dismissed on March 20, 2006) who became infamous for fabricating a series of experiments, which appeared in high-profile journals, in the field of stem cell research. Until November 2005, he was considered one of the pioneering experts in the field, best known for two articles published in the journal Science in 2004 and 2005 where he reported to have succeeded in creating human embryonic stem cells by cloning. He was called the "Pride of Korea" in South Korea.
Soon after the first paper was released, however, an article in the journal Nature charged Hwang with having committed ethical violations by using eggs from his graduate students and from the black market. Although he denied the charges at first, Hwang admitted the allegations were true in November 2005. Shortly after that his human cloning experiments were revealed to be fraudulent.
