Otto Hahn junior research group of the MPS at the MPI-PKS

Dynamical systems and Social Dynamics

home members research contact

What do we do?

We perform basic research to understand the dynamical mechanisms underlying different complex systems. We focus on simple models that lead to complex behavior due to the interplay between nonlinear-deterministic and stochastic processes. We apply these models to understand pardigmatic dynamical systems in Physics (e.g., chaotic billiards) and to explain the statistical properties of collective human activities (e.g., user activities in the Internet). Concrete examples of problems can be found in the research section and in the webpage of the members.
Motivated scientists interested in joining the group are encouraged to contact me, visit the webpage of the visitors program of the MPIPKS, and to consider possibilities of external funding such as the DAAD. Since 2012 we are not accepting candidates interested in performing the full Ph.D. in the group.
