One of the world's leading pioneers in examining ancient human DNA is David Reich, a professor of genetics at Harvard Medical School and a Howard Hughes Medical Institute investigator. For his work to changing ancient DNA data from a niche interest to an industrial process, he was designated one of 10 people who matter in all of the sciences in a 2015 article in Nature. For his computational finding of intermixing between Neanderthals and Homo sapiens, he received the Newcomb Cleveland Prize from the American Association for the Advancement of Science and the Dan David Prize in the Archaeology and Natural Sciences.
