Our group is now participating in the International Max Planck Research School for Cell, Developmental and Systems Biology (IMPRS- CellDevoSys). Please see the CellDevoSys page for the information on how to apply!
We have our first Postdoc - Johannes Taktikos! That means that the size of the group has doubled. Will try to keep this nice rate.
We have a new paper published that explains how one can use Langevin equations to describe various regimes of anomalous superdiffusive behavior: "Langevin description of superdiffusive Levy processes" by S. Eule, V. Zaburdaev, R. Friedrich, and T. Geisel. Visit the Publications page for a link to the paper.
It is fascinating to follow how individual cells can organize and develop complex and robust structures which are reminiscent of a living organism. Biofilms is one example of such systems. Read more on our Research page.
Welcome to the home page of the MPI-PKS Group Collective Dynamics of Cells. We just started in Dresden and will try to update this page regularly as the group grows and develops. Comments and suggestions are welcomed (via e-mail).
