Research

My main research interest is related to data-driven modelling of stochastic dynamical systems. This includes time series analysis and prediction, parameter estimation and system identification, software tool development.

Data-driven system identification is an interactive and systematic way of modeling dynamical system behavior by building mathematical models on the basis of experimental input/output data.

Due to inherent experiment based nature of the research, the developed methods and algorithms can be applied to a wide variety of dynamical systems and include problems such as data-driven modeling for control, system health monitoring and model validation.
