About

Bio

In my day job, I am an academic urologist affiliated with a large medical school. I take care of patients, teach medical students and residents, and do research. One of my areas of interest is to use technology to reach patients more efficiently without sacrificing quality.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
