Mrs. Skalli is a professor at Arts et Métiers ParisTech. She is also the director of Arts et Métiers ParisTech Laboratory of Biomechanics. She graduated from ENSAM (now Arts et Métiers ParisTech) in 1980 and got a PhD in mechanical engineering in 1983. Five years later she joined Laboratory of Biomechanics, where she is presently Professor and director, in charge of research team Biomechanics and orthopaedy. Her research is oriented towards understanding mechanical behaviour of musculoskeletal system with the aim (1) to assess normal behavior and mechanisms of degradation, (2) to improve implants and (3) to provide clinical tools for diagnosis and orthopedic or surgical treatment planning. She works mainly on geometric and mechanical modelling, with a strong link to in vitro experimentation and to in vivo quantitative clinical investigation. Wafa Skalli is particularly involved in spine biomechanics and scoliosis, in collaboration with more than 10 clinical teams, particularly that of Pr J. Dubousset (Paris), and others in France, US, Canada, Lebanon, Japan, Spain... She is presently member of IRSSD board (International Research Society for Scoliotic Deformities), honour member of ARGOS (European Association of Research Groups for Spine Osteosynthesis), and member of various other societies or scientific evaluation pannels.
