William Woodruff Roberts, MD

Professor, Urology
Professor, Biomedical Engineering


William W. Roberts, MD is Professor of Urology and Biomedical Engineering at the University of Michigan.  He earned a B.S. in Physics from the Massachusetts Institute of Technology in 1992, an M.D. from the Johns Hopkins University School of Medicine in 1997 and completed his urology training at the Brady Urological Institute at Johns Hopkins. He joined the faculty of the University of Michigan in 2004. His clinical practice is focused on endourology, and urinary stone disease.

He is the director of the Endourology Translational Research Laboratory which is focused on the optimization and safety of laser lithotripsy.  Dr. Roberts was also part of the multidisciplinary scientific team at the University of Michigan that developed histotripsy, a non-invasive, focused ultrasound technology that induces controlled cavitation to mechanically ablate targeted tissues within the body.

Dr. Roberts has presented his work at international and national meetings and has authored over 145 peer-reviewed publications. His research contributions have been recognized in the form of multiple grants and awards from the National Institutes of Health, American Urological Association Foundation, Coulter Foundation, Engineering and Urology Society, and Industry partners. He was the 2014 recipient of the prestigious AUA Gold Cystoscope Award.

Areas of Interest




  • High frequency laser lithotripsy for optimization of stone laser techniques and characterization and control of intraluminal temperature and pressure 
  • Development and refinement of instrumentation/devices to facilitate ureteroscopic stone treatment. 
  • Acoustic augmentation of shock-wave lithotripsy to enhance treatment and decrease collateral tissue injury. 
  • Histotripsy, specifically translation of histotripsy technology from the lab to clinical application for benign and malignant urological conditions including:
      • Benign prostatic hyperplasia
      • Prostate cancer
      • Renal masses
      • Urolithiasis
