I am a urologist with an expertise in the treatment of upper urinary tract diseases. I made my residency and fellowship at the University of Rennes in France. I made an additional fellowship in mini-invasive surgery at the University of Texas Southwestern Medical Center in Dallas. I am a professor at the University of Rennes where I have been appointed chairman of the department of urology in 2011. My clinical practice is dedicated to the treatment of urogenital tumours using laparoscopy and robotic assistance. I also have a clinical interest in endourology for the treatment of stones and tumours. My research is devoted to improve peri-operative outcomes after renal surgery and endoscopy. I also study prognostic biomarkers in kidney cancer. I am a member of the editorial board at large of European urology and I have published more than 200 scientific articles in peer-reviewed journals.
