npj Complexity is an online Open Access journal publishing high-quality peer-reviewed research in all aspects of complexity and aiming to foster dialogue across domains and expertise.

Our Editor-in-Chief, Prof. Laurent Hébert-Dufresne has been named the 2026 recipient of the German Physical Society’s Young Scientist Award for Socio- and Econophysics, which recognizes outstanding original contributions that use physical methods to advance understanding of socio-economic problems.

Collection "Variational, Nonequilibrium, and Optimization Principles of the Coevolution of Structure and Dynamics in Complex Systems" aims to gather theoretical, computational, and empirical contributions that advance the use of variational principles to explain and predict structure–dynamics interplay in complex systems.

This unique Collection aims to be an ongoing repository of resources for the pedagogy of complexity and for complexity in pedagogy.
