Dennis Lo Yuk-ming, 54, is one of Hong Kong’s foremost innovators in the realm of medical science. He was educated at Oxford University, the director of the Li Ka-shing Institute of Health Sciences and professor of medicine at Chinese University. He made a breakthrough discovery in DNA testing of pregnant women 30 years ago that led to the development of non-invasive testing for Down’s syndrome in the fetus. His discovery has benefited millions of women each year but raised an ethical dilemma about designer babies and DNA tests in our everyday lives. Lo, a winner of the Future Science Prize, considered the Chinese equivalent of the Nobel Prize, says the conditions are ripe for a biotech boom in the city.
