My main interest in research, as you might have already understood, is biomechanics, in its broadest meaning. I am fascinated by the possibility to describe and model the human (or animal) body structure and physiology in engineering terms.
Biomechanics is mechanics applied to biology. [...] The word "mechanics" has been identified with the analysis of any dynamic system. To people who call themselves workers in applied mechanics, the field includes the following topics:
- Stress and strain distribution in materials
- Constitutive equations which describe the mechanical properties of materials
- Strength of materials, yielding, creep, plastic flow, crack propagation, fracture, fatigue, failure of materials: stress corrosion
- Dislocation theory, theory of metals, ceramics
- Composite materials
- Flux of fluids: gas water blood and other tissue fluids
- heat transfer, temperature distribution, thermal stress
- Mass transfer, diffusion, transport through membranes
- Motion of charged particles, plasma, ions in solution
- Mechanisms, structures
- Stability of mechanical systems
- Control of mechanical systems
- Shock waves, and waves of finite amplitude
It is difficult to find anything living that does not involve some of these problems.

I am currently working in Exeter (UK) within the Biomedical Physics group at the university of Exeter. I am investigating the effects of needle puncture on the micromechanical characteristics of the intervertebral disc. More info to come soon!

I have been working three wonderful years within the BiomecAM chair research program on subject-specific musculoskeletal modelling at the Laboratoire de Biomécanique of the Arts & Métiers ParisTech. My work had three main objectives:
- Developing non-invasive mechanical characterization of the intervertebral disc with ultrasound elastography .
- Improving and validationg a finite element model of the spine for brace simulation in adolescent idiopathic scoliosis .
- Improving and validating an algorithm for the early detection of progressive idiopathic scoliosis

In November 2011 I had my dissertation defense and was awarded a PhD by the University of Caen with the highest distinction ("mention très honorable avec félicitations du jury"). The title of the dissertation was "In vivo measurement of tendon force by ultrasound: experimental and theoretical approach to acoustic propagation in tendon". You can download the thesis on this page.
I am currently continuing my work on axial speed of sound measurement in tendon, as a PostDoc, at the Laboratoire de Biomécanique et Pathologie Locomotrice du Cheval, Maisons-Alfort (France).

I worked for my PhD at the Laboratoire de Biomécanique et Pathologie Locomotrice du Cheval, Maisons-Alfort (France).
Briefly, the main results of my work (see my publications page) showed that tendon's Poisson ratio and mass density do not significantly affect the axial speed of sound variation that can be observed with load. This variation, and in general the tendon speed of sound level, are strongly related to tendon's elastic modulus or tangent modulus. The secondary objective of my work was to explore the interest of axial speed of sound measurements in the follow up of injured tendon; it turned out that the presence of a tendon lesion, and its progression in time, affect the axial speed of sound. Moreover, the results suggest that the seed of sound variation (or "normalized speed of sound") could be used to determine the injured tendon's elastic modulus. Therefore, speed of sound measurements bear complementary information to the standard clinical examination by ultrasonography.
This work lead me to the following tasks:
- Study the theory of ultrasound propagation in homogeneous orthotropic mediums and adapt it to a multilayer system, in order to define what exactly the ultrasonic probe measures and how.
- Characterize the elastic properties of equine tendons.
- Develop a device to measure the cross-sectional area of soft tissue samples during mechanical testing.
- Adapt the ultrasonic probe (which in origin measures the force applied to tendons) to the characterization of tendon lesions.
