The primary focus of my research is on urologic malignancies in general and specifically on prostate adenocarcinoma. At the clinicopathologic level, investigations on the surgical pathology of the prostate gland are performed including morphometric analysis of prostate cancer, studies on prostatic intraepithelial neoplasia, a putative precancerous proliferation, and histomorphologic studies on prostate cancer and its variants. Gene discovery and marker discovery in potential prostate cancer precursors and prostatic carcinoma are being pursued via gene expression profiling and whole genome sequencing.
