Research Summary

I study how genomic and epigenomic alterations affect tumor biology and patient outcomes. I have a particular interest in understanding how urological tumors develop resistance to targeted therapy. Recent projects have used large-scale genome sequencing to identify non-coding DNA structural variants associated with therapy resistance in advanced prostate cancer (Quigley Cell 2018) and a novel prostate cancer epigenomic disease subtype (Zhao Nature Genetics 2020). To achieve our goals, the laboratory works in close collaboration with physicians and laboratory investigators, and uses a wide variety of genome sequencing methods to study patient biopsy samples and preclinical models. This includes analysis of therapy resistance mechanisms in patients using liquid biopsy techniques and whole genome analysis of tumors. The lab has a long-term interest in understanding how inherited or somatic defects in homologous recombination repair (HRR) affect tumor genomes, and how to detect and overcome resistance to targeted PARP inhibitor therapy in patients with HRR-deficient tumors.
