Theoretical Physics of Complex Systems
Our research mission is to understand the nonlinear and stochastic
dynamics of complex systems, with a focus on adaptive biological
systems: evolution and brain.
A large part of our current research aims at understanding the
dynamical phenomena in and the functional role of sleep.
A second branch of research addresses evolutionary dynamics and systems
biology, as cyclic coevolution, finite populations, networks and
growth phenomena.
Methods
range from nonlinear dynamics and applied mathematics
to statistical physics, control theory,
information theory and biological physics.
In many cases we arrive at models that appear also in
quite different context in physical or biological systems,
but eventually also in social and economic systems
- and this is why complexity science also is fun!
If your have similar research interests and would like
to join our group: enquiries for new group members
or postdoctoral visitors are always welcome.
