RESEARCH FOCUS: My main research interest is using computer models and high-throughput ‘omics experiments to speed up the pace of biological discovery. I use statistical and bioinformatics techniques to model biological systems and develop regulatory networks that identify drivers of patient outcomes. Recently I have focused on deconvolution – determining which immune and stromal cells are present in gene expression data taken from tumor samples.
