Pawel Romanczuk holds a professorship on Complexity Research in Adaptive Systems at HU. For SCIoI, he works at the interface of applied mathematics, theoretical physics, and behavioral biology. He focuses on collective behavior of organismic systems. His research bridges analytical and synthetic sciences to study self-organization, evolutionary adaptations, and functional dynamical behavior.
