Professional Overview


I was born in Washington State and lived there until I left for college at Georgetown in Washington DC. After graduating magna cum laude at Georgetown I returned to the West Coast for medical school at the David Geffen School of Medicine at UCLA. Following medical school, I completed a 6-year urology residency at Stanford where I developed particular interests in the clinical care of patients with urologic cancers and research in cancer imaging. I then spent two years at UCLA as a urologic oncology fellow where I devoted all my time to gaining additional skills and experience in clinical care and research in urologic malignancies. Since then I have been at Stanford as an assistant professor in urology where I am applying the skills I gained in residency and fellowship to provide high-quality clinical care to patients with urologic cancers, in particular prostate and kidney cancer. I also continue to work to develop new methods to better diagnose and treat urologic cancers through research.

Scientific Focus

Current Research and Scholarly Interests

My primary interest is in improving prostate cancer diagnosis and treatment through MRI and image-targeted prostate biopsy. In collaboration with radiologists at Stanford, we are working to define the optimal role of MRI in prostate cancer. We hope to improve cancer imaging to the point that some men with elevated PSA may safely avoid prostate biopsy. For those who need biopsy, we are evaluating novel MRI-US fusion targeted biopsy, a technique that greatly improves upon the conventional biopsy method. More accurate prostate biopsy enables better decision making about treatment options such as deciding between active surveillance and surgery.

Moving beyond biopsy, I am interested in the use of imaging to select patients who are candidates for prostate cancer focal therapy. Focal therapy involves ablation of prostate cancers under image guidance without destruction or removal of the normal areas of the prostate and with less damage to important surrounding structures that are important for erectile function and urinary continence.

I am also interested in developing novel molecular imaging techniques such as near infrared fluorescence imaging to improve surgery for prostate and kidney cancer.
