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 until he was dismissed on March 20, 2006. He was considered a pioneering expert in stem cell research and even called the "Pride of Korea". However, he became infamous around November 2005 for fabricating a series of stem cell experiments that were published in high-profile journals in a case known as the Hwang affair. Hwang was best known for two articles published in the journal Science in 2004 and 2005, where he reported he had succeeded in creating human embryonic stem cells by cloning. However, soon after the first paper was released, an article in the journal Nature accused Hwang of 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 this, data from his human cloning experiments was revealed to have been falsified. On May 12, 2006, Hwang was charged with embezzlement and bioethics law violations after it emerged much of his stem cell research had been faked. The Korea Times reported on June 10, 2007, that Seoul National University fired him, and the South Korean government canceled his financial support and barred him from engaging in stem cell research. Hwang was sentenced to a two years suspended prison sentence at the Seoul Central District Court on 26 October 2009, after being found guilty of embezzlement and bioethical violations but cleared of fraud. On the same day, CNN reported that the scientist in 2006 had admitted faking his findings after questions of impropriety had emerged. He had his conviction upheld but his suspended sentence reduced by 6 months on 15 December 2010 by an appeals court in South Korea. In 2014, the South Korean Supreme Court upheld its 2010 ruling. Since the controversy, Hwang has maintained a relatively low profile, but continues to work in scientific fields. As of September 2020, he worked at the Sooam Bioengineering Research Institute in Yongin, Gyeonggi Province, leading research efforts into creating cloned pig embryos and embryonic stem cell lines. In February 2011, Hwang visited Libya as part of a US$133 million project in the North African country to build a stem cell research center and transfer relevant technology. The project was canceled due to the 2011 Libyan civil war. In November 2015, a Chinese biotech company Boyalife Group announced that it would partner with Hwang's laboratory, Sooam Biotech, to open the world's largest animal cloning factory in Tianjin. The factory would aim to produce up to one million cattle embryos per year to meet the increasing demand for quality beef in China.
