Mechanics of rupture applied to soft biological tissues

Developing original experimental methods based on in-situ experiments observed by X-Ray tomography or full-field optical methods (e.g. sDIC), to understand and characterize the rupture mechanisms of biological tissue (applications in aortic dissection, hernia prevention), with a focus on the role of the microstructure. Finite element method with cohesive elements or the phase-field approach are also used to explore and rank which parameters may influence the outcome of these pathologies.

Mechanical interactions between medical devices and the body

Using finite element analysis to assess the external and internal actions of textile-based medical devices and relate them to potential therapeutic effects. Applications include knee braces, lumbar belts, shoes, hernia repair meshes. Experimental identification methods are also used to better characterize these devices.

Computer-assisted surgery for endovascular interventions

Implementing numerical tools involving mechanical simulations to predict and assist the deployment of stentgrafts for the treatment of aortic abdominal aneurysms, or stents for intracranial aneurysms. We aim at preserving the accuracy of the results, while accelerating the speed of computations to enable clinical applications.

I teach to engineer and master students in my field of expertise:

• Application of the finite element method
• Reduced-order modelling and design of experiments for biomedical applications

I teach in the “Biomechanics” course for BMed Master diploma and tutor multiple student projects in relation with industrial partners.

I also teach an introduction to biomechanics in a school of osteopathy (CIDO).

I studied at the European School of Materials Engineering in Nancy, France, and had the opportunity to spend one year at the Luleå University of Technology, Sweden, where I obtained a Master of Science in 2010. I then joined the Center for Biomedical and Healthcare Engineering in Ecole des Mines de Saint-Etienne, France, and graduated as a PhD in 2013 in the field of orthotic biomechanics. Subsequently, I went abroad for 2 years as a post-dosctoral fellow in University College Dublin, Ireland, to study the mechanical behaviour of brain tissue. I published several papers on mechanical characterization of brain tissue.

Since 2016, I work as a research engineer in the Center for Biomedical and Healthcare Engineering in Ecole des Mines de Saint-Etienne, France.
