Sir John James Skehel (born 27 February 1941) is a British virologist celebrated for his long-standing research on influenza viruses and for leadership of one of the United Kingdom's principal medical research institutes. He is an Emeritus scientist at the Francis Crick Institute in London and holds fellowships in major scientific academies (FRS, FMedSci).

Research focus and contributions

Skehel's scientific work has concentrated on the biology of influenza viruses, particularly the structure and function of viral surface proteins that mediate binding to host cells and membrane fusion. His laboratory pursued experimental and structural approaches to understand how viral proteins change during infection, how they provoke immune responses, and why influenza viruses continually evolve to escape immunity. These lines of inquiry have direct relevance to vaccine design and to explaining patterns of antigenic drift in seasonal influenza.

Career and leadership

From 1987 until 2006 Skehel served as Director of the National Institute for Medical Research (NIMR) at Mill Hill. Under his stewardship NIMR sustained a broad portfolio of fundamental biomedical science and training. In 2016 the institute was incorporated into the newly created Francis Crick Institute, where Skehel remains associated in an emeritus capacity. Throughout his career he combined laboratory research with administrative roles and support for national research priorities.

Notable themes and impact

  • Clarifying mechanisms by which influenza haemagglutinin binds receptors and triggers membrane fusion.
  • Investigating structural changes in viral proteins that affect antigenicity and host range.
  • Contributing to scientific leadership, mentoring younger researchers, and shaping institutional research directions.

Skehel's work has influenced how virologists think about virus–host interactions and vaccine targets. He has been recognized by election to senior scientific societies and by a knighthood for services to biomedical science. His combination of laboratory discovery and institutional leadership exemplifies a career that bridged fundamental virology and public-health-relevant questions.
