Post-doctoral position for the development of nonlinear microscopy in the field of cancer diagnostics
30-11-2023 - Offres de CDD - Post-doc

Funding : ERC Consolidators grant

Duration : 36-month – Starting date September 2024

Salary : ≥ 2400€ negotiable

Supervisor : Dr. Sandro Heuke, Chargé de Recherche at the CNRS

Research team : MOSAIC

Address : Institut Fresnel, Av Escadrille Normandie-Niémen, 13397 Marseille Cedex 20, France.

Our mission
Our rent advances in coherent Raman microscopy allow for the real-time generation of artificially stained images of cancer samples which previously required time-consuming histopathological staining procedures. These images serve as feedback for surgeons to guide cancer surgery. As the main challenge, the examination of thick cancer samples is currently impossible, as all excitation light in coherent Raman microscopy is scattered forward and must pass through the sample. Within this project, you will develop a new coherent Raman technique called coherent Stokes Raman scattering (CSRS) microscopy. As the game-changer, CSRS will send the signal photons directly into the backward direction and, therefore, enable the investigation of thick, non-transparent cancer samples. Moreover, we will use CSRS’ backscattering property to record the CSRS spectrum of tissue at unprecedented speed levels using novel spectrometer concepts and multi-focus or wide-field illumination approaches. From these CSRS spectra, a precise diagnosis of the cancerous tissue will be derived by machine learning algorithm. Your mission is to set up and characterize these novel microscopy techniques and evaluate their functionality on cancer tissue.

Your Profile

Attitude : For you, research is a vocation and not just a source of income. High levels of initiative, creativity and curiosity are expected from you.

Willingness to perform : During university education you were always in the top 20% and you should have at least 2 major publications as first author.

New algorithmic approaches for Fluorescence Diffuse Optical Tomography in the second biological window
19-10-2023 - Offres de CDD - Post-doc

Researcher offer : New algorithmic approaches for Fluorescence Diffuse Optical Tomography in the second biological window (SWIR)

Principal Investigator : Dr Anabela Da Silva, PhD, Senior researcher at CNRS - Email :

Research team : DiMABio, Institut Fresnel / CERIMED

Address : Institut Fresnel, Av Escadrille Normandie-Niémen, 13397 Marseille Cedex 20, France. Work carried out in partnership with KAER LABS (Nantes) and Institut pour l’Avancée des Biosciences (IAB, Grenoble)

Funding : Fondation AMIDEX, 12 months

We are offering a 12-month post-doc position (AMIDEX funding) in the field of modeling and image processing for optical biomedical imaging. The work will take place at the Institut Fresnel in Marseille, within the DiMABio team, as part of a collaboration with the Optimal platform of the Institut pour l’Avancée des Biosciences (IAB) in Grenoble, and Kaer Labs in Nantes, for the development of a fluorescence tomography system in the second biological window NIR II or SWIR (Short Wave InfraRed 900-1700 nm). The candidate’s mission will be to develop 3D reconstruction algorithms for the localization of fluorescence sources detectable in vivo in mouse models.

Scientific background and objective :
Optical biomedical imaging is a fast-growing non-conventional imaging technique. Fluorescence Diffuse Optical Tomography (FDOT) is a non-invasive imaging technique capable of detecting and quantifying localized fluorescent sources in deep organs of living organisms (rodents). Conventional FDOT uses non ionizing radiation in the visible to near infrared spectral range (<900 nm, NIR I), in which biological tissues are relatively unabsorbent but highly scattering. As part of this project, we intend to explore the second therapeutic window, known as NIR II or SWIR (shortwave infrared) (900 nm to 1700 nm), where biological tissues are highly absorbent, mainly due to their high water content, but have lower scattering coefficients than in the visible range or NIR I, giving rise to the hope of higher resolution images, while accessing penetration depths compatible with the dimensions of small rodents (1 to 2 cm). More specifically, the project concerns the development of a reconstruction algorithm using fluorescence images from a small animal fluorescence imaging system similar to that described in publications [1-4], but in the "NIR-II" or "SWIR" spectral range (1000 to 1700 nm), co-developed by Kaer Labs, IAB and Institut Fresnel. This algorithm must : i) be based on the numerical resolution of a light
propagation model capable of taking into account the high absorption and scattering levels of biological tissues at these wavelengths (Radiative Transfer Equation) ; ii) take into account the technical characteristics of the instruments (acquisition geometry, type of sensor and source, fluorescence filter, etc.). The candidate will be able to draw on preliminary work and numerical tools already implemented (work started two years ago), as well as on the expertise and infrastructures of the teams.

The algorithm developed will then be applied to the detection of new organic (cyanine derivatives) and inorganic (gold nanoclusters) SWIR contrast agents [5] with cancer-specific motif targeting functions. The in vivo biological behavior of these contrast agents will be evaluated after administration in mice. First, their in vivo biodistribution will be assessed in healthy mice, then their tumor-targeting capacity will be evaluated in mouse models of cancer [6].

The work will thus comprise the following 3 phases :
 Implementation of numerical tools, in particular the development of a Radiation Transfer Equation solver using Monte Carlo simulations or the Finite Element Method, optimized for coupling to a reconstruction algorithm.
 Experimental validation on phantoms
 Pre-clinical study

Key words : Inverse problems, Diffuse Optical Tomography (DOT), Radiative Transfer Equation, Small Animal Imaging, Fluorescence in NIR I (Near InfraRed 600-900 nm), NIR II or SWIR (Short Wave InfraRed 900-1700 nm)

Candidate profile :
As the models and methods for solving the equations are known, this project requires strong skills in numerical modeling (solving the Radiation Transfer Equation using numerical or stochastic methods), applied mathematics and information processing. The multi-disciplinary context, at the interface between physics and biomedical research, calls for an independent and open-minded candidate, capable of taking experimental and biological constraints into account. The main skills required for the project concern knowledge of physical models, scientific computing (numerical analysis for PDEs, optimization, algorithms, Deep Learning and HPC), signal and image processing. No specific chemistry or biology skills are required, but candidates should be open to the prospect of contributing to these experiments.

Programming languages : C/C++, Python, MATLAB, VTK, CUDA.

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

Post-Doctoral position in the development of X-ray texture tomography to study biomineralized tissue
03-05-2022 - Offres de CDD - Post-doc

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
