MVEX01-18-33 Large-scale regulatory network models for analysis of cancer

​​Network models derived from genomic profiles of cancer tumours can provide insight into genetic drivers behind a disease, provide biomarkers for diagnostic prediction and be used to propose new treatment regimes. Graphical lasso estimates are widely used; they can be adapted to model disease subtypes and to incorporate prior information. However, it is a well known that large-scale estimates are highly variable which limits their interpretable value. In addition, the data correlation matrices that the models are derived from can be dominated by structures/processes that aren't very interesting from a disease-predictive standpoint. Recently, researchers have looked into approaches that improve estimation precision for large-scale models (see this article). 

In this project, you would apply the root-based graphical lasso to cancer data and investigate if this enhances disease-relevant components in the generated networks.
