Boolean networks

Boolean networks are qualitative models of regulatory processes that represent the state of a node by a simple bistable switch, e.g. genes can be transcribed or not transcribed. Although being highly abstract, Boolean networks have proven to approximate the real nature of gene-regulatory processes well.

The research of our group covers the complete process of construction, analysis and simulation of the networks. This includes approaches for the binarization of time series measurements, inference of networks from such time series, literature-based network assembly, simulation and attractor search.
