Research Interests
I direct several institutional and national biospecimen banking efforts, mostly in the context of cancer therapeutic trials. Using the resources available through the CAP-accredited, Siteman Cancer Center Tissue Procurement Facility, biospecimens are collected from clinical sites throughout the world, received, processed, and distributed for integral and correlative science biomarker studies. As part of this larger effort, I also supervise the development and deployment of software applications for biospecimen banking and biorepository operations.
My research laboratory is interested in identifying the genomic alterations that contribute to tumor cell metastasis in breast and lung cancer, with the goal of developing advanced genome-based diagnostics to detect, classify, and eradicate metastatic tumor cells to improve long-term patient outcome. By performing genomic analyses of primary tumors, metastatic lesions, circulating tumor cells (CTCs), disseminated tumor cells (DTCs), and cell-free, circulating DNA (cfDNA) from cancer patients, we are identifying biomarkers that are both prognostic for outcome and predictive of therapeutic response. Our goal is to better understand the process of genomic evolution of tumor cells and to leverage this information to develop therapeutic targeting strategies, in collaboration with clinical and surgical oncologists, to mitigate metastatic disease.
