Francis Collins, a geneticist and director of the US National Institutes of Health for 12 years, retired from his position on 28 February, with a tribute to his colleagues and the institution that they support. “The National Institutes of Health is the world’s foremost medical research institution. It has been rightfully called the ‘crown jewel’ of the federal government for decades. It has been the greatest honour of my life to be part of this institution in various roles over the last four decades,” he said in a statement.
