Le descriptif de l’offre ci-dessous est en Anglais

Niveau de diplôme exigé : Thèse ou équivalent

Fonction : Post-Doctorant

Mission confiée

Photoplethysmography (PPG) is a measurement of the amount of light absorbed by tissues, including blood vessels. This measurement depends on the amount of blood present in the tissues. The PPG is thus considered as a measure of the volume of blood (arterial and venous) present at a certain moment in the tissue. This project aims at estimating blood pressure in the humanan wrist (systolic/diastolic) from PPG measurements, through the development of mathematical models of PPG measurement and suitable estimation methods.

 

 

Principales activités

The post-doctoral project proposes to address this problem via a hybrid approach which builds on a hierarchy of mathematical models (PPG and blood flow measurement) of increasing complexity: from a simple 0D model (Windkessel RC) to a 3D poroelastic model of the tissue which links the PPG measurement to the level of tissue perfusion.

Main activities:

  • Bibliographic studies
  • Development of mathematical models
  • Development of numerical methods
  • Data-simulation coupling
  • Numerical implementation (FELiScE software)
