Deux offres de post-docs et une offre d'ingénieur dans l'équipe Modélisation et Imagerie Numérique

Domaines : Analyse d'images et trajectographie/Statistiques spatiales/Apprentissage automatique/Développement logiciel

The "Modeling and Digital Imaging" team at Institut Jean-Pierre Bourgin (Versailles, France), has two post-docs and one engineer positions available to work within the frame of national or international research projects involving collaborations with different groups of biologists. These positions are fully funded by the French National Agency for Research (ANR) through three distinct projects.

We are looking for strongly motivated young scientists or engineers aiming at developing their skills in time-lapse 3D biological image analysis, spatial statistics, and/or machine learning.

Engineer (1,5 year) 
Analyse d'images et statistiques spatiales de l'organisation du noyau dans les réponses mécaniques
Based on the methodology developed in the lab1,2, the recruited engineer will design and implement new image analysis pipelines to quantify and model plant nuclear responses to mechanical stresses. Depending on personal profile and motivations, the project may encompass developing new software solutions.
This work will be conducted within the frame of the ANR Blanc MechaNuc 2021-2025.
Project in collaboration with ME Chabouté, CNRS Strasbourg

Post-doc 1 (2 years)
Analyse d'images et apprentissage statistique pour la cartographie spatio-temporelle du cycle cellulaire
Based on previouswork in the team3, the recruited post-doc will establish a computational framework based on image analysis and statistical learning to reconstruct and analyze a 3D+t atlas of subcellular dynamics in cycling plant cells and to model cell division4,5.
This work is part of the ANR Blanc PlantScape 2021-2024.
Project in collaboration with David Bouchez (IJPB, Versailles) and Marie-Cécile Caillaud (RDP, Lyon)

Post-doc 2 (2 years)
Analyse d'images et modélisation des mouvements chromosomiques lors de la méiose
The recruited post-doc will extend the methodology developed in the lab for the spatial modeling of object patterns1,2 for the analysis of chromosome movements in 3D within meiotic plant nuclei.
This work will be part of the ANR PRCI MeioMove 2021-2024.
Project in collaboration with Mathilde Grelon (IJPB, Versailles) and Arp Schnittger (U Hamburg, DE)
