C.J. Budd — professor of Applied Mathematics at the University of Bath and Chair of Mathematics at the Royal Institution of Great Britain. ..I am interested in the theory, application and computation of nonlinear problems (linear problems are for cissies) with special interest in problems which arise in industry. Much of my recent work has been on the development of accurate adaptive methods for solving nonlinear parabolic equations based upon the application of ideas from the theory of Lie groups, which inherit the dynamics and associated conservation laws of the underlying partial differential equations.
