My research focuses on patterns of gene expression, gene regulation, and gene product interactions that can be inferred from large collections of mRNA expression data.  This approach is useful for identifying normal interaction and regulatory connections between genes as well as the disruption of these connections in complex diseases such as cancer.  Bioinformatics approaches allow these connections to be easily extended into the context of biological pathways in order to understand global changes with respect to disease states or treatment.  I’ve collaborated extensively with other Principal Investigators in the KCC to establish automated analysis pipelines for genes, gene signatures, and interaction profiles that provide informative readouts of pathway function and dysfunction associated with disease states.  

Future plans include the automation of a publically accessible web-based tool that provides a user-friendly readout of genes, gene signatures, and interaction profiles across multiple phenotypes, disease states, and therapeutic interventions.  As this tool evolves, it will be useful for designing and implementing classification algorithms to assist disease diagnosis and guided therapy.
