Dr. Westphalen became interested in an academic career during medical school, when he first got involved with research, having received support for two years from the Brazilian National Council of Research, Scientific Initiation Institutional Program. During the next two years after graduation, Dr. Westphalen served the Brazilian military as a primary care physician and was an Internal Medicine post-doctoral scholar at the Federal University of Rio Grande do Sul School of Medicine, Brazil. He subsequently joined and completed his radiology residency in 2001 at the Institute of Cardiology of Rio Grande do Sul/Cardiology University Foundation and Moinhos de Vento Hospital in Porto Alegre, Brazil. In 2003 Dr. Westphalen came to UCSF as a visiting research scholar, and in 2005 he completed a Clinical Fellowship in Abdominal Imaging and then a one-year Clinical Radiology Research Fellowship, after which he was recruited as a faculty member in the Department of Radiology. During this time, he intensified his academic activities, including research and teaching of trainees and practicing physicians. In 2011, he received his Master’s Degree in Clinical Research from the UCSF Department of Epidemiology and Biostatistics, and in 2012 he completed his PhD in Surgical Sciences, Urology, through the Federal University of Rio Grande do Sul, Brazil. Dr. Westphalen has a shared appointment with the UCSF Department of Urology, directs the UCSF Department of Radiology Clinical Prostate MRI Program, and chairs the UCSF Department of Radiology MR Safety Committee.

Clinical Interests

Dr. Westphalen is internationally known as an expert in imaging of genitourinary diseases, in particular of prostate cancer. He is the point-person and department's liaison to other specialties, in particular urologists, for all imaging matters. Furthermore, he is continuously working to engage his radiologist colleagues, trainees, and technologists, to assure the high-quality of scans. Clinical duties relate mainly relate to UCSF patients, with approximately 20% consultations and reinterpretation of studies performed at outside institutions across the country and around the globe.

Research Interests

Dr. Westphalen's research is focused in the use of advanced imaging technologies to diagnose and treat prostate cancer patients with the ultimate goal of improving patients’ outcomes. He is a member of an established clinical research team, the Prostate Cancer Imaging Group (PCIG), which encompasses several researchers from the UCSF Departments of Radiology and Biomedical Imaging and Bioengineering and Therapeutic Sciences. The team investigates various in-vivo and ex-vivo imaging techniques, in particular magnetic resonance modalities, and the merging of these tools with several other technologies including, robotics and high-frequency focused ultrasound (HIFU), for treatment and diagnosis of prostate cancer. The PCIG and the Department of Urology have long-standing, innovative collaborations in many research projects.
