Prof. Dr. Theo Geisel pursues the research topics of his former Department of Nonlinear Dynamics with an emeritus group. He studies the nonlinear dynamics of complex systems, e.g. to clarify the function of biological neuronal networks or to forecast the spreading of epidemics based on the statistics of human mobility. In a current research project on musical time series he investigates e.g. the role of microtiming deviations for the swing feel in jazz. Professor Geisel was appointed director at the MPIDS in 1996 - jointly with a chair for Nonlinear Dynamics at the University of Göttingen - and became emeritus in September 2016. He founded the Bernstein Center for Computational Neuroscience (BCCN) Göttingen and headed it for many years.
Prof. Toennies continues the research of his former department "Molecular Interactions" as an Emeritus. His present focus is on intermolecular potentials, quantum fluid helium and hydrogen clusters, helium atom scattering from crystal surfaces, and quantum flow dynamics of solid helium.
