Research Interests

My research focusses on stochastic analysis and its applications. In particular, I am working on the qualitative behavior of stochastic dynamical systems such as systems of stochastic differential equations (ordinary, partial, functional), their numerical methods and stochastic difference equations. The applications range from mechanical engineering (random vibrations, oscillators), laser physics (injection locking), finance (interest rates, dynamic asset pricing), marketing (innovation diffusion) to biology and ecology (random epidemics, population models).
