Networks: A language for understanding complex systems

To this workshop the organizers Andreas Engel, Claus Hilgetag, Marc-Thorsten Hütt invited guests from biology and social sciences to neuroscience and psychology to explore networks, a formal language (and set of computational tools) to analyze, interpret and understand complex systems.

This relatively new field of interdisciplinary research brings together formalisms from graph theory and computational data analysis with mechanistic modeling approaches often used in statistical physics. The workshop is a forum for discussing recent trends in this field and seeing which questions network approaches help to solve. The audience is interdisciplinary with networks as a unifying common topic.
