Network methodologies for understanding gene coexpression in the human brain.


The PhD student will investigate algorithmic and statistical methodologies for improving the reliability, testability, causal inferability, and extensibility of gene co-expression networks. These methodologies will be applied to and validated within a multi-disciplinary cross-college collaboration that for several years has been working on improving our understanding of the regulation of gene expression in multiple regions of the human brain.
