I mainly treat patients with genitourinary cancers including prostate, kidney, bladder, testicular and penile cancer.  My goal is to be attentive and devoted to my patients who are often dealing with complicated health problems. I try to personalize my care because every patient is different. I believe the future is promising because new treatments are being discovered every day. I am involved in clinical trials done through Duke University.  Clinical trials are designed to provide patients with access to the newest possible treatments. I am also part of our multi-disciplinary cancer team including urologic oncologists, geneticists, radiation oncologists, pathologists, radiologists, and other specialists.  I grew up in Cary and did all of my medical training in the Research Triangle Park area. I feel honored to practice in the same community I have lived in for more than twenty-five years.

Prior to arriving at Duke, I was faculty at UT Southwestern where I had a dual appointment at the North Texas VA for 10 years. During this time, I was one of the highest volume robotic VA surgeons treating veterans with urologic cancer in addition to my clinic practice at UTSW. I joined the Urology department at Duke in 2024. At Duke, I have continued my focus on urologic oncology, specifically prostate, bladder and kidney cancer. I have a particular interest in prostate cancer. I was one of the earliest adopters of a novel surgical technique termed the Retzius Sparing Prostatectomy, which allows for the earlier return urinary control. I have further adopted a novel technique for the treatment of localized prostate cancer known as irreversible electroporation (IRE). This technique is a form of focal therapy for carefully selected patients. The advantages of IRE include less urinary and sexual side effects than conventional prostate cancer treatments. In addition, my clinical expertise includes advanced robotic reconstruction of the upper urinary tract. These procedures involve using segments of bowel or buccal grafts (inner lining of the cheek) to reconstruct damaged ureters.

As a medical oncologist and hematologist, I treat patients with common adult solid and hematologic cancers. My passion for cancer treatment is deeply rooted back to my childhood when I witnessed loved ones suffering from this devastating disease. As such, I share with patients and their families the feeling of desperation, pain and stress. In my view, cancer treatment is not only a medicine but also an art, as a physician needs to be sensitive to both the patient's physical, and emotional needs to keep their hope for getting better alive. I have particular interests in gastrointestinal malignancies, like esophageal, stomach, small bowel, colon, pancreatic, biliary and liver cancer. I provide my patients with evidence-based and the most advanced treatment options, including participating in clinical trial opportunities.
