Content, Learning Outcome and Preconditions
In this course, we will introduce deterministic modeling approaches for biochemical reaction networks. These modeling approaches can be used to describe, e.g., signal transduction and metabolic processes. For these models the respective parameter estimation problem will be formulated and methods will be presented to solve these problems. As parameter estimates carry uncertainties due to limited amounts of data and measurement noise, we furthermore provide methods for a rigorous analysis of parameter uncertainties. This is crucial to evaluate the model uncertainties as well as the predictive power of models.
The participants will gather hands-on experiences with parameter estimation and uncertainty analysis, including the implementation of own models and estimation procedures in MATLAB. The estimation methods are presented in the context of biological processes, but the approaches are applicable in many other fields.
1) Modeling of biochemical reaction networks in a nutshell ( 2 lectures)
1.1) Introduction of biochemical reaction networks (including several examples)
1.2) Mass action and Michaelis-Menten kinetics
1.3) Reaction rate equation (RRE)
(The RRE is a system of ordinary differential equations which can be used describe the dynamics of reaction networks. It is widely used in chemistry, biochemistry and biology. In this lecture we develop methods for systems of ordinary differential equations and illustrate them using different RRE models.)

4) Bayesian parameter estimation for RREs (3 lectures)
1) Bayes theorem and Bayesian statistics
2) Markov chain Monte-Carlo sampling
3) Bayesian confidence intervals for parameter estimates and predictions
5) Properties of estimators (e.g. bias and variance) (1 lectures)
