About the research centre or Inria department

Le centre de recherche Inria de l'Université Grenoble Alpes regroupe un peu moins de 600 personnes réparties au sein de 23 équipes de recherche et 7 services support à la recherche.

Son effectif est distribué sur 3 campus à Grenoble, en lien étroit avec les laboratoires et les établissements de recherche et d'enseignement supérieur (Université Grenoble Alpes, CNRS, CEA, INRAE, …), mais aussi avec les acteurs économiques du territoire.

Présent dans les domaines du calcul et grands systèmes distribués, logiciels sûrs et systèmes embarqués, la modélisation de l'environnement à différentes échelles et la science des données et intelligence artificielle, Inria Grenoble - Rhône-Alpes participe au meilleur niveau à la vie scientifique internationale par les résultats obtenus et les collaborations tant en Europe que dans le reste du monde.


Inria, a French research institute dedicated to digital sciences, employs 2,600 people from the best universities in the world, and takes up the challenges of computer science and mathematics. Inria has 9 centers in France, including the Inria Grenoble research center, which employs nearly 730 people. Inria is organized into “project teams” which bring together researchers with complementary skills around a focused scientific project.

The ANR Inora project in collaboration between Inria Grenoble, the Mines de St Etienne and the University Hospital of St Etienne aims to understand the mechanisms of pain in the foot of patients with rheumatoid arthritis. In particular, the project seeks to highlight the links between certain physical factors such as forces or areas of internal and external pressure on the foot with the sensation of pain.


To carry out this task, a finite element modeling method 1 of the foot is implemented by our partners at the Mines de St Étienne. Finite element methods require very fine 3D geometric models of the musculoskeletal system to produce realistic results. It is planned to acquire CT and/or MRI scanners of the foot to construct such models.

If these medical imaging methods show a good contrast between the bones and the soft tissues, certain zones nevertheless remain ambiguous for various reasons such as losses of bone density or, conversely, welds between distinct bones.

The candidate will therefore have to set up a semi-supervised segmentation method for foot scanners which makes it possible to segment and identify each bone, i.e. to extract the surfaces of each bone in the form of mesh from a dense and regular grid of voxels, then assign a name to each element.

This process should be carried out reliably using an iterative process involving an automatic component and manual corrections as light as possible.

Eventually, the generated dataset can be used as a training base for a convolution network that can operate fully automatically 2.

Main activities

A variety of activities will be required on this position:

  • Review of the state-of-the-art in medical imaging segmentation methods
  • Segmentation software testing
  • Design of a semi-supervised segmentation software
  • Software implementation
  • Manual dataset segmentation
  • Result evaluation
  • The position will be co-supervised by Julien Pansiot (Kinovis platform engineer, SED) and Sergi Pujades (Morpheo project team). The candidate will also work in close collaboration with doctoral students and interns from the Morpheo team as well as from the Mines de St Etienne and the staff of the CHU de St Etienne.


    The candidate must hold an engineering degree, Master's degree in computer science, or equivalent.

    Very good foundations in computer vision, medical imaging or 3D modeling as well as C++ and Python programming are expected.
