Work within my laboratory focuses on dissecting underlying genetic/epigenetic mechanisms of aggressive prostate cancer. For this work, we utilize in vitro genetically modified human and mouse cell lines and 3D organoid cultures as well as in vivo genetically engineered mouse models coupled with innovative technology including next generation sequencing approaches. Our overall goal is to identify novel genomic/epigenomic mechanisms which will lead to discovery of biomarkers and therapeutic targets for clinical testing, with a specific focus on tumor and immune cell lineage plasticity in prostate cancer.
