Senior CNRS Research Director (DR1)

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).

Yohan Payan cosupervises with J. Ohayon the Biomechanics of Living Organs Serie (Elsevier) and is Associate Editor of the Clinical Biomechanics journal, responsible for papers focusing on soft tissue biomechanics.

Yohan Payan represents TIMC inside the OrthoSim Joint Laboratory, gathering TIMC (CNRS & UGA), the company TwinSight Medical and the hospital CHU Grenoble Alpes. He is also administrator of the Société de Biomécanique.
