Dr. Hao Nguyen is a urologic oncologist at the UCSF Helen Diller Family Comprehensive Cancer Center. He specializes in the early detection, diagnosis and treatment of prostate cancer, kidney cancer, bladder cancer and other cancers of the genital and urinary organs. He performs open (traditional), robotic, laparoscopic and endoscopic surgeries.

Nguyen earned a bachelor's degree in molecular cell biology from the University of California, Berkeley in 1999. To further his training as a physician-scientist, he then joined the dual medical and doctoral degree program at the Boston University School of Medicine, in its biochemistry and molecular medicine department. He completed his general and urologic surgery training at the University of California, Davis, followed by a fellowship in urologic oncology at UCSF under the guidance of esteemed specialists Dr. Peter Carroll and Dr. Maxwell Meng. At the end of his fellowship, Nguyen joined the faculty at the UCSF Department of Urology.

Nguyen has authored more than 25 peer-reviewed scientific articles and book chapters, and has presented his research findings at national conferences. In 2015, he received the prestigious Department of Defense Physician Research Training Award to continue his work on how cancer cells are able to survive cancer treatments via a mechanism known as the stress response. He hopes his findings will lead to new treatments that target this response.
