CIBSS Research Project:

The goals of the group which mainly consists of theoretical physicists are two-fold. On the one hand, we develop mathematical methods for analyzing and modelling biological systems, most often based on dynamic time-resolved data. This includes parameter estimation and uncertainty analysis for dynamical systems. On the other hand, we apply these methods in close collaboration with experimentalists in the field of signalling research and synthetic biology. Integrative mathematical models enable to look at biological systems in a way that traditional biological approaches and techniques does not allow. The final goal is not to have a mathematical model – a model is nice to have – but to use the model in order to unterstand biology.  By this approach, we aim to help to turn the life sciences from a qualitative descriptive into a quantitative predictive science.
