 Research Activities

I study nonlinear dynamical systems and complex systems with interest in complexity of spatiotemporal chaotic dynamics. My current research are focused on random dynamical systems approaches to noiseinduced phenomena, timeseries analysis of dynamical systems with large degrees of freedom, and information theoretic analysis of spatiotemporal chaos. Applications of nonlinear dynamical systems theory to problems in information theory, computation theory, prediction and control, are also put in perspective.
