About Me

I am a surgeon who specializes in caring for patients with genitourinary cancers (prostate, kidney, bladder, testis, and adrenals). My primary interest is the development of innovative minimally invasive surgical techniques — such as laparoscopy, robotic-assisted laparoscopy, and image-guided therapies — to treat genitourinary cancers. I am an expert in the use of advanced laparoscopic surgical techniques to treat patients with urologic cancers.

The types of surgery I perform include: nerve-sparing laparoscopic or robotic radical prostatectomy (removal of the prostate) for prostate cancer; laparoscopic radical cystectomy (removal of the bladder) and urinary diversion for invasive bladder cancer; and laparoscopic partial nephrectomy (removal of the tumor only and preserving the rest of the kidney) for kidney cancers.

In addition to our dedicated nursing staff, I am fortunate to have world-class colleagues from medical oncology, radiology, and radiation oncology with whom I work closely in a multidisciplinary fashion to offer the best treatment for our patients.

In my clinical research I compare minimally invasive surgery to conventional open surgery in terms of cancer control and impact on the quality of life of our patients. I am also very interested in finding ways to improve the efficacy and quality of urologic surgery and assessing its impact on surgical outcomes.

After completing a fellowship in urologic oncology and advanced laparoscopic oncology at Memorial Sloan Kettering, I joined the Urology Service in 2004. I am board certified by the American Board of Urology, a member of the Society of Urologic Oncology, the American Urological Association, the European Association of Urology, and other national and international societies. I teach advanced laparoscopic and robotic surgery to members of the European Association of Urology and the American Association of Urology. Additionally I serve as a reviewer for a number of peer-reviewed urology and cancer journals, and lecture internationally on the role of minimally invasive surgery in treating of prostate and kidney cancers.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
