My research on dynamical systems has included work on vibro-impacting systems, population dynamics, nonlinear phenomena in power networks and economic modelling. The common theme in all of the above is the presence of discontinuities in the mathematical models.
My work in numerical analysis has been the analysis and development of adaptive timestepping algorithms for both Ordinary and Stochastic Differential Equations.
Recent work in the area of economics and financial modelling has focused on the development and analysis of mathematical models that operate under more realistic assumptions than those used in neoclassical economics. In particular we attempt to mimic the ways in which human psychology and institutional market defects (such as herding, moral hazard and perverse incentives) affect financial markets.
I am co-organizing a 3 week-long workshop in Glasgow in June 2009 on `The Limits to Rationality in Economics and Financial Markets' as well as a shorter one in January 2009 restricted to memory effects in economics. More details can be found here
