Steven Cowley is director of the Princeton Plasma Physics Laboratory (PPPL) and a professor of astrophysical sciences at Princeton University. A theoretical physicist and international authority on fusion energy, he led the United Kingdom Atomic Energy Authority from 2009 to 2016. Much of Cowley’s research career has been devoted to modelling and understanding plasma turbulence in nuclear fusion, a phenomenon that must be controlled to achieve stable fusion. Cowley is a fellow of the Royal Society and of the Royal Academy of Engineering. He was knighted by the Queen of England in June 2018 for his services to science and the development of nuclear fusion.
