Members of the Soft Tissue Biomechanics (STBio) department are experts in biomechanical modeling and experimentation on soft biological tissues. Within the Joint Research Unit (UMR) SAINBIOSE (Inserm U1059, sainbiose-lab.fr), they develop digital twins for biology, medicine, and surgery in the cardiovascular and osteoarticular fields.

Research unit
The scientific activities of the department staff are fully affiliated with the Joint Research Unit (UMR) 1059 – SAINBIOSE, and more specifically with the LBTO team (Osteoarticular Tissue Biology).
This integration ensures a unique synergy between:
- The School’s engineering
Contribution of modeling and instrumentation skills. - Inserm research
Scientific framework, HCERES evaluation, and access to clinical challenges. - Medical innovation
Partnerships with the Saint-Étienne University Hospital (CHU) and the industrial sector.
This integration of biology, engineering, and health positions the department as a key player in biomedical research, linked to clinical and industrial challenges.
