Doctoral Course Syllabus

Title: Characterisation of Metabolic Phenotypes via Data Integration

Duration: 8 hours (January 23-24)

Teacher: Chiara Damiani

Course Overview:

Technological advancements in the determination of complete genomic sequences and their annotation, and the well-explored biochemistry of metabolic transformations have facilitated the thorough reconstruction, on a genome-scale, of the metabolic network of many target organisms. The conversion of metabolic networks into a mathematical representation has established a framework upon which a mechanistic understanding of the metabolic genotype–phenotype relationship can be articulated. While a metabolic reconstruction is unique to the target organism, one can derive many different condition-specific models from a single reconstruction. Mapping of ‘omics’ into these networks enables the analysis of the ‘omics’ in the context of the curated knowledge about the target organism.

This doctoral course aims to provide participants with the basic knowledge of the metabolic network reconstruction and analysis framework. The focus will be on the analysis of metabolic pathways through the integration of various data types, including gene expression, proteomics, and metabolomics. The course will cover theoretical concepts as well as practical applications using user-friendly web-based platforms such as Esher and Galaxy. 

By the end of the course, students will have acquired the ability to independently navigate and assess the strengths and limitations of the current state-of-the-art methods and the increasing list of accomplishments of the vibrant and growing field of metabolic network reconstruction and analysis.
