This website introduces my academic and some personal interests. I am a researcher in biomechanics, currently working in Paris, France, at the Institut de Biomécanique Humaine Georges Charpak, Arts et Métiers. I specialize in spine biomechanics, with a focus on scoliosis and intervertebral disc.
My research focuses on the multiscale biomechanical characterization of soft tissues and the development of quantitative imaging tools to improve the diagnosis and treatment of musculoskeletal pathologies, with a particular emphasis on spinal deformities. My work integrates experimental testing, non-invasive imaging, and patient-specific numerical modeling to bridge the gap between fundamental tissue mechanics and clinical application.
Spine Biomechanics & Scoliosis Research
Spine Biomechanics & Scoliosis Research
My research in Adolescent Idiopathic Scoliosis (AIS) aims to move beyond simple 2D measurements like the Cobb angle toward a comprehensive 3D characterization of the deformity. Key contributions include:
• The Severity Index (S-index): A predictive biomarker developed from 3D spine phenotypes (incorporating torsion and axial rotation) to distinguish between stable and progressive curves at an early stage.
• Barycentremetry: Using 3D reconstructions of the body envelope from biplanar radiographs to analyze the distribution of centers of mass and gravity-induced axial torque. I found that scoliotic patients maintain their segmental centers of mass near the gravity line despite their deformity, but show abnormally high torque at junctional vertebrae.
• Patient-Specific Modeling: Validating Finite Element Models (FEM) to simulate the effects of brace treatment and surgical interventions. These models help optimize orthotic design and evaluate the stress distribution in complex spinal constructs.
Non-Invasive Tissue Characterization & Quantitative Imaging
Non-Invasive Tissue Characterization & Quantitative Imaging
A significant portion of my work involves developing and validating ultrasound shear wave elastography to assess the mechanical properties of deep-seated and anisotropic tissues in vivo. I have established reliable protocols for measuring the stiffness of:
• Intervertebral Discs (IVD): Demonstrating the feasibility of measuring the annulus fibrosus in children and adults to identify biomechanical markers for idiopathic scoliosis and disc degeneration.
• Muscles and Fascia: Quantifying the shear modulus of lower limb muscles, the multifidus, and the thoracolumbar fascia at rest and during passive stretching to provide baselines for neuromuscular disorders.
• Tendon and Abdominal Wall: Assessing the patellar tendon and linea alba, including how factors like breathing and joint angle affect clinical measurements.
