  • Post-Doc position | Migration of complex shaped particles in micro-channels:
Summary: Analytic processes for micro-organisms detection and identification in fluids (e.g., microbial control in food industry, biological fluids analysis …) are of major interest for society in a large range of contexts from the lab scale to industrial processes. They often require a preliminary step of separation in order to isolate microbial cells, presumed pathogens, from the other particle components and/or to concentrate them before identification. The samples often contain a mixture of suspended particles and several micro-organisms species with different morphologies and sizes. An easy and portable way to achieve preliminary sorting or separation of these micro-organisms can be done based on their migration under flow in micro-channels.
The aim of this project is to build a relevant tool to predict migration of complex-shape particles that mimic micro organisms (ranging from model spheres to flexible fibers) in given microfluidic geometries (rectangular micro-channels) under hydrodynamic laminar regimes (to prevent cell damage). The work will be focused on numerical development of the Force Coupling Method that accounts for fluid-particle interaction.

  • PhD Thesis | Migration of complex shaped particles in micro-channels:
Complex shaped particules migration in micro-channels
Migration de particules de forme complexe dans des micro-canaux
Main goal: to improve the trajectory prediction of inert non-spherical particules seeded inside a liquid micro-flow. The obtained results on these complex particules will contribute to the development of innovative micro-devices for separation and analysis of bio-particules.
Objectif: améliorer la prédiction des trajectoires de particules inertes non sphériques soumises à un écoulement liquide dans des micro-canaux.

  • PhD Thesis ESR-9 MIGRATE | Gas-Liquid Surface Micro Separators - VOCs trapping:
Main goal: Development of a miniaturized gaseous formaldehyde micro-analyser based on gas uptake into an aqueous reagent coupled to fluorescence or colorimetric detection in microfluidic devices. Liquid-surface-gas interactions will be modeled for the optimization of the gas uptake operating at low gaseous sampling flow. An upgraded version of an existing operational prototype for formaldehyde quantitative detection will be developed and tested.
