Post-doctoral position in the development of x-ray texture tomography to study biomineralized tissue
03-05-2022 - Fixed-term contract - Postdoc

The crystallographic texture is a major determinant for the behaviour of materials. Despite this importance, appropriate, quantitative methods to study the crystallographic texture in biomaterials in 3D are missing. In the framework of a project funded by the European Research Council (ERC Starting grant TexTOM), our group is aiming to develop texture tomography as a quantitative tool to study the crystallographic texture in 3D, based on previous work. We finally want to use it to study the mechanical behaviour of a functionally graded, hierarchically organized biomaterials, the bone-tendon insertion. This work is embedded in the larger research context of the COMiX team, whose expertise lies in the development of characterization techniques for complex crystalline materials with a specific focus on biomineralization.

Place : Institut Fresnel (Aix-Marseille University, CNRS, Ecole Centrale Marseille)
Duration : 36 months
Requirements :
 PhD degree with sound expertise in synchrotron science, scientific computation, X-ray diffraction, crystallography, biomineralization or a related discipline
 Very good knowledge in object-oriented programming, familiarity with Python is a bonus
 Highly-developed critical and analytical skills
 Capability to work in an interdisciplinary, international team

Application : Candidates are requested to submit a cover letter explaining shortly the relevance and motivation of the application, a detailed CV, 2 major publications and 3 academic references. Send it to

Postdoc in Microscopy & Computational Imaging
03-01-2022 - Fixed-term contract - Postdoc

The EquipEx+ project IDEC "Computational Imaging and Detection" coordinated by Institut Fresnel focusses on the new generation of optical imaging and detection instruments based on innovative co-design, bridging instrumentation and computational approaches. In this context, Institut Fresnel brings together competencies in conceptual and numerical developments and in advanced instrumentation.
 The candidate will develop new fluorescence imaging microscopes for adaptive scanning and optimized polarized microscopy in collaboration with the research teams and Platform PHOTONICS members. The candidate will be in charge of the design based on existing proofs of principles, the implementation of these novel microscopy tools, and their operation in collaboration with partners from laboratories and industry, in particular in the field of cell and developmental biology

Place: Institut Fresnel, Marseille
Conditions: Start date before 31/03/2022
Duration: 24 months

Post-doc : Procédé de structuration et de polissage par laser CO2 de composants optiques en silice.
13-12-2021 - Fixed-term contract - Postdoc

Ces dernières années, la fabrication de composants optiques a connu une évolution importante avec, d’une part la demande pour des optiques dites ‘free form’, c’est-à-dire dont la surface n’est ni plane ni sphérique, et d’autre part le développement de nouveaux procédés de fabrication tels que la structuration laser ou la fabrication additive. Les optiques ‘free form’ ou les optiques diffractives permettent de résoudre de nombreux problèmes de mise en forme de faisceaux laser.

Place : Institut Fresnel (Marseille) and sometimes CEA CESTA (Bordeaux)
