Description Different types of information can be represented in the shape of networks in order to model a biological system. A network is a graphical representation of different biological entities (nodes) and their relationships (edges): the meaning of the nodes and edges used in a network representation depends on the type of data used to build the network. Some of the most common types of biological networks are: protein-protein interaction networks, Metabolic networks, Genetic interaction networks, Gene / transcriptional regulatory networks and Cell signalling networks.
In this project we will focus on metabolite-metabolite association networks that can be built from metabolomics data: the ultimate goal is to characterize the properties of these networks and to answer to questions like: Which topological measures best reflect a set of metabolites participating in the same pathway? Are metabolite-metabolite association networks scale free? Do they exhibits small world properties? Which measures better described metabolites associated with a disease?
At the end of the project you will have gained ample experience in network analysis, network topology, statistics and in handling and modelling complex information.
