# Terry Lyons

Terry Lyons is the Director of the Oxford-Man Institute. He is the Wallis Professor of Mathematics at the University of Oxford, a Fellow of the Royal Society, President-Designate of the London Mathematical Society, and one of the UK’s leading mathematicians, having made a number of contributions to stochastic analysis. He has been named Schramm Lecturer for 2014 by the Institute of Mathematical Statistics.

His interest in stochastic analysis relates particularly to the control of non-linear systems driven by rough paths. Prime examples of such systems are provided by stochastic differential equations and stochastic systems.

His research on ‘rough paths’ has founded a new field, stimulating an enormous amount of work, allowing breakthroughs in many areas such as numerical analysis. He has a deep understanding of the role of risk in financial markets where he is known for his work on managing uncertainty in volatility, and for developing cubature methods as new tools allowing more efficient numerical modelling.
