Complex systems of interactive agents are of interest in many research areas. Examples of such systems are social networks or contact networks, through which rumors or viruses can spread from individual to individual, and engineered networked systems such as the power grid, through which cascading failures can lead to large blackouts. Network science studies the behavior of such system by representing pairwise interactions as edges in a network.

As a result, many research areas have begun to consider heterogeneous interactions via network structures. We will discuss two research directions of interest:

1) Dynamical processes on networks: analyzing dynamics that govern time-varying behaviors of nodes or edges states.

2) Graph signal processing: extending spectral domain analysis to signals on a graph.
