My research covers the following areas: statistical mechanics and critical effects in non-equilibrium systems, magnetism on macroscopic and mesoscopic length scales, reaction kinetics and non-linear dynamics.
As an example of the first and second items, we examine the role of self-organized criticality in magnetic domain formation. Currently we examine magnetization reversal processes and magnetic multilayer structures. In reaction kinetics, the research is directed towards finding formulae for rate constants when traditional rate theory fails.
In non-linear dynamics, we attempt to determine the kind of states in which complex systems settle down, starting from unstable configurations.
