Professor Gil Dubernard trained in Obstetrics and Gynecology with a specialization in surgery at the Assistance Publique Paris Hospital from 1997 to 2007. He defended his PhD Thesis in 2008 on the influence for fetal microchimerism on mammary adenocarcinomas associated with pregnancy. His clinical work was initially focused on the management of gynecological and mammary cancers, then his focus progressively moved toward the diagnosis and treatment of endometriosis. He mouved at Croix-Rousse University Hospital (Lyon, France) in 2007. In 2010 he was named University Professor-Hospital Practitioner and in 2015 was appointed manager of the Obstetrics Gynecology department. Since then, his work has been more and more focused on the diagnosis and management of endometriosis. He has developed a new technique for diagnosing endometriosis, which is known as 3D Rectosonography. He is a « surgeon sonologist ». The development of this ultrasound diagnostic technique enables him to consider management techniques other than surgery for rectal endometriosis. In 2016 Professor Dubernard joined LabTAU (INSERM 10-32 unit). They have carried-out their first global phase I study on the treatment of rectal endometriosis with Focused Ultrasound in collaboration with the company FocalOne, the global leader in robotic energy-based therapies. Their Focal One platform has been granted Breakthrough Device designation by the US Food and Drug Administration (FDA) for the treatment of deep infiltrating endometriosis (DIE). He also introduced in 2020 in France the radiofrequency myolisis technic performed by laparoscopy under sonographic control. He is always searching for the latest technological innovations to push the limits of minimally invasive surgery
