Dr. Catalona joined the Northwestern faculty in 2003. He is known for having been the first to show that a simple blood test that measures levels of prostate-specific antigen (PSA) is the most accurate method for detecting prostate cancer and for having developed the ""free"" PSA test as a means of improving the accuracy of prostate cancer screening.
Dr. Catalona is currently conducting research into the genetics of prostate cancer which could lead to new tests for the disease as well as possible new means of treating or preventing prostate cancer. He specializes in prostate cancer surgery and is recognized as an expert in performing the ""nerve-sparing"" radical prostatectomy that can preserve sexual potency.
In addition to his appointment as Professor of Urology, Dr. Catalona also serves as Director of the Clinical Prostate Cancer Program of Northwestern's Robert H. Lurie Comprehensive Cancer Center.
