Research Interests
My research has focussed on the dynamics and pattern formation in complex systems and dynamical networks. In particular, I explore the collective behaviour of large interactive systems, ranging from networks of coupled nonlinear oscillators to models of coupled biological and chemical systems. I have also focussed on chaos-inspired design of novel computing paradigms, as well as exploiting the interplay of noise and nonlinearity for enhanced reliability of logic operations. The ideas proposed by us are known in current literature as 'Chaos Computing' and 'Logical Stochastic Resonance'.
