Breast Cancer

Research Interests

My academic training is in bioinformatics, machine learning, statistics and genomics with a focus on integrative computational analysis of high throughput genomic data. My recent work has focused on integrative analysis of RNA and DNA sequencing to identify genomic changes associated with benefit to targeted therapy. Previously I developed methods to identify prognostic association of genome wide DNA methylation changes in breast cancer in collaboration with clinical and bench scientists. I also developed a computational framework (InFlo) that integrates genome-wide copy-number and gene expression data with biological pathway definitions to identify dysregulated pathways in individual patient tumors that are associated with clinical outcomes in breast and ovarian cancer.
