Professor Sir John Ball
Senior Fellow of Hong Kong Institute for Advanced Study, City University of Hong Kong
Professor at Heriot-Watt University, Edinburgh, UK
Foreign Member of the French Academy of Sciences
Fellow of the Royal Society, UK
Member of the Academia Europaea
He moved to Heriot-Watt in 1972 on an SRC postdoctoral fellowship which enabled him to spend an extended period at Brown University, where he began work on the existence of solutions to the equilibrium equations of nonlinear elasticity, as well as furthering his interest in infinite-dimensional dynamical systems. The recipient from 1980-85 of an SERC Senior Fellowship, he has held Visiting Professorships at the University of California at Berkeley, at the Université Pierre et Marie Curie, Paris, at the Tata Institute of Fundamental Research, Bangalore, at the Institute for Advanced Study, Princeton, and at the University of Montpellier II.
He was elected a Fellow of the Royal Society of Edinburgh in 1980, a Fellow of the Royal Society in 1989, an Associé Etranger of the Académie des Sciences in 2000, a Fellow of the Institute for Mathematics and its Applications in 2003, a Foreign Member of the Istituto Lombardo in 2005, a Foreign Member of the Norwegian Academy of Science and Letters in 2007, a Member of the Academia Europaea in 2008, and a Fellow of the American Mathematical Society in 2012. Other awards include the 1981 Whittaker Prize of the Edinburgh Mathematical Society, the 1990 Keith Prize of the Royal Society of Edinburgh, the 1995 Naylor Prize in Applied Mathematics of the London Mathematical Society, the 1999 Theodore Von Karman Prize of the Society of Industrial and Applied Mathematics, the 2003 David Crighton Medal of the Institute of Mathematics and its Applications and the London Mathematical Society, the 2006 Royal Medal of the Royal Society of Edinburgh, the 2009 Sylvester Medal of the Royal Society, the 2012 John von Neumann Lecture and Prize of SIAM, the 2018 King Faisal Prize for Science, the 2018 Leonardo da Vinci award of the European Academy of Sciences, Honorary Fellowship of St John’s College, Cambridge in 2005, Honorary Membership of the Edinburgh Mathematical Society in 2008, and Honorary Doctorates from the Ecole Polytechnique Fédérale de Lausanne, Heriot-Watt University, the University of Montpellier II, the University of Sussex, the University of Edinburgh, the Université Pierre et Marie Curie and the University of Bucharest. He was a Council Member of the Engineering and Physical Sciences Research Council from 1994-1999, President of the Edinburgh Mathematical Society from 1989-90, and of the London Mathematical Society from 1996-1998 and in 2009, and President of the International Mathematical Union from 2003-06. From 2011-2018 he was a member of the Executive Board of the International Council for Science.
John Ball's main research areas lie in the calculus of variations, nonlinear partial differential equations, infinite-dimensional dynamical systems and their applications to nonlinear mechanics. In solid mechanics, he is especially interested in the mathematics of microstructure arising from phase transformations in solids, using models based on nonlinear elasticity, where the problem of predicting microstructure morphology is related to deep unsolved questions of the multi-dimensional calculus of variations such as understanding quasiconvexity. A more recent research interest is in the mathematics of liquid crystals.
