Dynamics Group - Institute for Structural Dynamics
We focus on complex system dynamics. One research field is complex dynamics in machines and structures, which we analyze through network, complexity and machine learning methods. A second field is nonlinear wave physics, including ocean 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.
