Dynamics Group - Institute for Structural DynamicsWe focus on complex system dynamics. One research field is complexity in machines, which we analyse through network, complexity and machine learning methods in structural Dynamics. A second field is nonlinear wave physics, including rogue waves. A third field is highly efficient physics based computing in engineering. All our work is conducted with national and international partners. Prof. Hoffmann, who directs the group, is also a visiting professor at Imperial College London.
