Genetics and Biomarkers
Project leader for the SABOR study which seeks to identify biomarkers for prostate cancer. Among the markers being studies are genetic variants, miRNAs, serum proteins and urine markers. Looking for markers associated with risk and progression. Focused on both identifying new markers and validating existing markers.
