Research Activities

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