Senior CNRS Research Director, co-head of the Bioméca team.

Research themes
His main research interests concern the biomechanical modeling of soft tissue and their integration into medical devices used to assist surgeons for planning (pre-operative surgical assistance) or to guide them during surgery (intra-operative guidance). The corresponding applications concern plastic and maxillofacial surgery, breast cancer treatment, neurosurgery, orthopedics and rehabilitation, based on organs (face, tongue, eyes, breast, brain) or musculoskeletal models (lower limb, including bones and soft tissues such as muscles, tendons, fat and skin).
