Systems Biology of Molecular and Cellular Networks

We investigate the spatial and temporal dynamics of molecular and cellular regulatory networks

  • experimentally (mostly through collaborations but increasingly in house)
  • through mathematical modelling and model analysis techniques

The main research line on molecular networks focuses on the regulation of cell growth and proliferation, especially dealing with cell cycle regulation and its connection to aging, to the circadian clock and to spatial control of cell growth. We also develop tools to predict changes in the complexome upon perturbations by drugs or disease.

On the cellular networks track we investigate cell-cell interactions in yeast colonies and use the results of this approach in combination with theoretical ideas to design and synthetically establish multicellular computing colonies.
