Further Information

Statistical analyses, mathematical modelling and bioinformatic algorithms are essential for exploiting the full information content of experimental data, for drawing valid conclusions and for the integration of information from different sources. We develop, optimize and apply methods of mathematical modeling, statistical and bioinformatic analysis in systems biology and systems medicine.

Our mission is providing experiences and access to the latest computational methodology and to improve these methods by novel generic or project-specific extensions. We focus on a broad spectrum of measurement techniques applied in molecular biology, in particular on proteomics, sequencing methods and cytometry.

Many existing computational methods are not well-tested in application settings and their applicability is frequently seriously delimited and/or they have to be tailored to specific research questions. We therefore perform comprehensive benchmark studies for assessing the performance of computational approaches and for deriving guidelines of optimal selection between competing algorithms.

Our research is very relevant for CIBSS because the quantitative analysis of signaling compounds is essential. Moreover, novel modelling approaches are required for investigation and understanding of cellular signaling at multiple scales.
