Abstract. Complex networks have been used to model almost any real-world complex systems. An especially important issue regards how to relate network structures to their dynamics, which would contribute not only to the better understanding of such systems, but also to the prediction of important dynamical properties from specific topological features. In this talk I will review related research developed recently in my group. In particular, I will discuss the concept of accessibility, a new measurement integrating topology and dynamics, and the relationship between frequency of visits and node degree in directed modular complex networks. Analytical results will be provided that allow accurate prediction of correlations between structure and dynamics in systems underlain by directed diffusion. This methodology will be demonstrated with respect to the macaque cortical network. I will also briefly discuss some other applications of these types of complex networks analysis approaches such as to transportation in cities, bone structure, and epidemics in morphologic systems.
