Professor John Shepherd MA PhD FIMA CMath FRS is a Professorial Research Fellow in Earth System Science at the National Oceanography Centre at the University of Southampton. He is a physicist by training, but has worked on a wide range of environmental issues, including the transport of sulphur dioxide in the atmospheric boundary layer, the dispersion of tracers in the deep ocean, the assessment & control of radioactive waste disposal in the sea, the assessment and management of marine fish stocks, and most recently on Earth System Modelling and climate change. His current research interests are in climate change and the natural variability of the climate system on long time-scales, and in the development and application of intermediate complexity models of the Earth climate system, especially for the interpretation of the palaeo-climate record.
From 1989–1994 he was Deputy Director of the MAFF Fisheries Laboratory at Lowestoft, and the principal scientific adviser to the UK government on marine fisheries management. He has been Professor of Marine Science at the University of Southampton since 1994, and from 1994–1999 he was the first Director of what is now the National Oceanography Centre. From 2001 to 2010 Professor Shepherd was also a Deputy Director of the Tyndall Centre for Climate Change Research. He is a Fellow of the Institute of Mathematics and its Applications, and was elected a Fellow of the Royal Society in 1999.
He has extensive experience of international scientific assessments and advice in controversial areas such as fisheries management and radioactive waste disposal, as well as climate change, and has taken a particular interest in the interaction between science, economics, and public policy.
