Dr. Geoff Cottrell began his career as a radio astronomer at Cambridge, observing colliding galaxies. He then moved to plasma physics, to Culham Centre For Fusion Energy and the Joint European Torus (JET) project, working on magnetically confined plasmas, hotter than the centre of the Sun, where he identified a new form of super-thermal radio emission from fusion alpha-particles. He was Director of the Culham International Summer School for Plasma Physics from2006-2011. He has now returned to his first love, astrophysics, and in recent years has worked with Chris Lintott at Oxford University on the citizen science project, Galaxy Zoo. He is a Fellow of the Royal Astronomical Society, and visiting scientist at Rutherford Appleton laboratories, and at the OxfordUniversity Astrophysics Department. Less
