Responsabilité et missions
Head of the experimental platform for the biomechanics department.
Activités de recherche
– Mechanical characterization of soft tissues and textiles
– In-silico evaluation of the mechanical interactions between medical devices and the human body
– Advanced experimental techniques (2D and 3D full-field measurement methods, FEMU identification)
– Applications to the fields of musculoskeletal and cardiovascular biomechanics, computer assisted surgery.
I teach to engineer and master students in my field of expertise.
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. My research topics involve mechanical characterization of biological tissues and textiles, finite element modelling of the interaction between human body and medical devices, and computer assisted surgery. I work in close collaboration with industrial partners and physicians.
