Professor Hayday is the Kay Glendinning Professor of Immunobiology at the Francis Crick Institute, King’s College London, co-Leader of the Clinical Academic Grouping in Genetics, Rheumatology, Immunology, Infection, and Dermatology at Guy’s Hospital, and a Senior Group Leader at the London Research Institute of Cancer Research UK.He obtained his PhD in tumour virology from Imperial College London and then moved to work at MIT with Susumu Tonegawa, before his appointment to the Yale University faculty, where he rose to become a full professor in 1997 receiving the William Clyde DeVane Medal, Yale’s highest honour for scholarship and teaching. In 1998, he returned to Guy’s Hospital and King’s College in London.Adrian’s research interests include unconventional T cells, the regulation of tissue inflammation and the control of carcinogenesis. He was co-discoverer of the gamma-delta T cell antigen receptor, a discovery that generated widespread interest in immune cell function within tissues, and tumour immune surveillance. Together with long-standing collaborators, Prof. Hayday has succeeded in identifying critical roles for gamma-delta cells in primary immunoprotection against solid tumours, and in immunoregulation, particularly within tissues. He is internationally renowned for his work in immunology and has published over 200 papers.He was elected a fellow of the Academy of Medical Sciences in 2002, and won the King’s College Award for Business in 2009. He has been a member of numerous advisory Boards including the Scientific Advisory Board of Medimmune, and is currently a member of the Scientific Advisory Boards of HS Lifesciences and ImmunoQure. He also advises a number of bodies, including the Wellcome Trust and CRUK where he is Chair of the Science Committee, responsible for the oversight of basic and translational cancer research programmes.
