Robin Lovell-Badge is Senior Group Leader and Head of the Laboratory of Stem Cell Biology and Developmental Genetics at the Francis Crick Institute (United Kingdom). His laboratory co-discovered the mammalian sex-determining gene Sry in 1990, and he has since focused his research on the genetic pathways leading to male-female differences. He is also interested in the development of the nervous system, and the biology of stem cells within the early embryo, the central nervous system and the pituitary. Author of over 200 papers, reviews and commentaries, he is an Honorary Professor of Biosciences at University College London, a Distinguished Visiting Professor at the University of Hong Kong, a Fellow of the Academy of Medical Sciences and the Royal Society, and a member of the Board of Directors of the Public Library of Science (PLOS). He holds the Louis Jeantet Prize for Medicine, among other distinctions, and was named a Commander of the Order of the British Empire (CBE) in the 2018 New Year’s Honors list.
