Fredric W. Taylor is Halley Professor of Physics at Oxford University, a Fellow of Jesus College, Oxford and a member of the Oxford Physics Department, where he was head of Atmospheric, Oceanic & Planetary Physics for 21 years. He was educated at he Duke of Northumberland's School, Alnwick, the University of Liverpool (B. Sc. With First Class honours in Physics), and Oxford University (D. Phil. In Atmospheric Physics). After graduating he spent ten years in the USA, in the Space Science Division, of the Jet Propulsion Laboratory, California Institute of Technology, in Pasadena. While there he was Principal Investigator on an experiment which flew on the Pioneer Venus Orbiter in 1979, making the first systematic study of the meteorology of the atmosphere of Venus, and became involved in the Galileo mission to Jupiter. He returned to England in 1980 to take up his present position and is currently participating in a number of planetary and Earth Observation space experiments, including Cassini-Huygens, Mars Reconnaissance Orbiter and Venus Express. He and his colleagues at Oxford and overseas also do theoretical work and modelling on problems in atmospheric and oceanic physics, such as ozone depletion, the greenhouse effect and climate change.
