The aim is to introduce this broad field of research to young researchers, in particular Ph.D. students, postdoctoral fellows and junior researchers who are interested and eager to tackle new challenges in the study of complex networks. The workshop will consist of tutorial courses given by some of the world experts in the field, each consisting roughly of 3 hours of lectures. This workshop immediately precedes the workshop Statistics for Complex Networks and provides a solid introduction for the general topical area of that workshop.
