1. Lectures on complex networks
Background 
Network theory has recently emerged as a major tool relevant for very different disciplines ranging from physics, applied mathematics, to biology, computer sciences and almost all areas of social sciences such as geography, urbanism and sociology. This lecture will address the characterization of large networks, the most important models and the effect of the network structure on various dynamical processes. This course does not require specific knowledge and is designed to be accessible to anyone with a minimal background in statistical physics, probability, and graph theory.

Outline of the course 
Note that this outline is mainly indicative and I will try to keep it updated
