Research at Centre for Nonlinear Studies

The research at the Centre for Nonlinear Studies has covered several directions in nonlinear science, such as statistical physics, condensed matter physics, biophysics, and nonlinear optics. Our current research focus is on analysis and modeling of dynamical processes of complex systems.

Complex systems are everywhere, ranging from physics, life science to human society. Recently, due to the development of experimental and information technologies, there is an rapid accumulation of massive data for biological and social systems. It has been shown that most real complex systems are characterized by complex networked interaction and highly fluctuating dynamical activity. Complexity research now calls for new methodologies to obtain a more quantitative understanding of various complex systems by integrating the approaches of theoretical modeling and computer simulations with experimental or empirical data.

Our work emphasizes understanding the structure-dynamics-function relationship in complex network systems by studying the impact of complex network topology on various dynamical processes, such as synchronization of oscillators, avalanches of neural firing, and individual and collective human dynamics.

One important research direction of the Centre is analysis and modeling of complex network structure and activity in neural systems. We carry out research in close collaboration with neuroscientists, using the approaches of oscillatory dynamical networks and covering broad scales from network of neurons to interacting functional brain regions and cognitive performance.

The research activity includes but not limited to the following topics:

Complex neural networks

self-organized activity
