Mapping Complexity

By M. Ángeles Serrano and Marián Boguñá

Fundamental Science for Society FS2

Complex systems, such as societies, the Internet, the human brain, molecular networks within cells, international trade, and many others, are ubiquitous and around us. We are using networks to uncover the fundamental principles governing their structure, function, evolution, adaptability, and for modeling and predicting their behavior.

Ongoing Projects

We develop mathematical models and computational tools to investigate a wide variety of real complex systems, ranging from biological to economic and socio-technological systems. We characterize these systems using massive datasets.
