Advanced tomographic reconstructions and multispectral analysis using tomodensitometry: towards an improved physical and chemical characterization of materials in Earth and Environmental Sciences
Institut national de la recherche scientifique (INRS), Québec, Canada

The Institut national de la recherche scientifique is a university dedicated to research and training at the graduate level. French is the official language. The Centre Eau Terre Environnement focuses its activities on the sustainable management of water and earth resources.

The Laboratoire multidisciplinaire de tomodensitométrie pour les ressources naturelles et le génie civil (LTRG), located at INRS–Eau Terre Environnement, is equipped with a medical CT-scanner allowing for the non-destructive analysis of samples such as cores from terrestrial, lacustrine or marine drilling. This unique facility in Canada allows for the 3D acquisition of data in sedimentology, paleoclimatology, archeology, geology and other related fields. Most of the samples analysed using the LTGR facility are denser and have a higher atomic number than the biological tissues usually studied with this kind of instrument in the medical realm. These differences make the characterization of these sample difficult (density, chemical composition, 3D structure).

In order to improve the analytical ability of the LTRG CT-Scanner, two projects are offered: 1) to develop a physical model of the image production line and to fit it within an iterative reconstruction algorithm in order to obtain images that are more quantitatively accurate, and that potentially have a better spatial resolution; 2) to develop multispectral techniques to chemically characterize samples analysed with LTRG CTScanner. These projects will be carried out in collaboration with the Department of Physics, Physical Engineering, and Optics of Laval University.

Eventually, the output of these research projects will be used to implement innovative protocols that will increase the amount and the quality of information provided by the CT-Scanner benefiting several current and future research projects in material sciences, archeology, geology, paleoclimatology, and the Canada Research Chair in Environmental Sedimentology (e.g., sediment erosion and transport, coastal erosion).



STUDY PROGRAM: Master’s or PhD in Earth Sciences at INRS. For more information.

SCHOLARSHIP : A $21,000 per year scholarship is available for 3 years (PhD) or $ 18,000 for 2 years (Master). A tuition exemption program is available for international students. Holding or being eligible to an NSERC or FRQNT scholarships will be an asset.

DESIRED QUALIFICATIONS : Have a university degree in physics, physical engineering, or geological engineering. Have strong computer skills and a thorough knowledge of Matlab, C++ and/or Python. Knowledge of French or intention to learn French, as well as an interest for Earth Sciences, are assets but not requirements.

HOW TO APPLY : Send an application package in one PDF file to including:

  1. a curriculum vitae
  2. a cover letter
  3. all university transcripts
  4. a list of practical and technical skills
  5. names and address of two referees

Review of applications will begin on 30 November 2017 and continue until the position is filled.
