I have played a prominent role in the field of urologic research, publishing extensively on urinary tract infection (UTI), inflammation and incontinence. Among my major contributions are several clinical techniques for both male and female incontinence, including an innovative urethral sling procedure. Along with colleagues, I was the first to describe the systemic changes of bacteria binding that subsequently cause UTIs in women and developed a novel technique for patient-based management of them. I have published more than 400 peer-reviewed articles and is currently a member of the NIH Multi-Site Collaborative Research Project on male chronic pelvic pain syndrome (prostatitis). I have maintained continuous NIH funding since 1978 and contributes regularly to international panels to establish guidelines for management of UTIs.

My clinical and research interests involve urinary tract infections, prostatitis, and chronic pelvic pain syndrome.
