The properties of living organisms depend on integrated biochemical machinery involving thousands of distinct molecular species. Studying such systems requires fruitful abstractions such as that of ‘networks’. The main task now is to discover how the structure of biological networks determines function. A huge body of theory for complex network analysis has been developed by sociologist and physicist. Most of these tools can be readily applied to gain insight into the global functional organization of biological networks.

We currently analyze a Gene Network from the organism yeast. Network properties such as in- and out-degree distributions, path-lengths, clustering, motifs, centrality, giant component structure, communities etc., are investigated.
