Post-doctoral fellow in fluid mechanics in human cerebrovascular system H/F

Description de l'offre

Preeclampsia (PE) is a specific pregnancy complication characterized by maternal hypertension and placental inflammation, leading to short and long-term health consequences for both mother and fetus. Although clinical symptoms generally disappear after delivery, mothers remain at high risk of stroke, chronic hypertension, and cognitive disorders, later in life. Recent animal model studies show that this condition damages the cerebrovascular system during pregnancy, with persistent long-term lesions, particularly affecting the integrity and function of the blood-brain barrier (BBB).

The central hypothesis is that gestational hypertension, linked to placental inflammation, alters the mechanical and functional properties of BBB vessels, depending both on their size (large, medium, small vessels) and location within the brain. To explore these mechanisms, the project uses experimental measurements combining:

- Systemic hemodynamic data acquired in animal models (measured at the tail in animals);

- Brain MRI data (measuring blood flow, blood volume, and mean transit time, influenced by intracranial pressure).

- Numerical simulations of cerebrovascular biomechanics, using the CATHARE system fluid dynamics software (see ).

Project description: As a postdoctoral researcher within an interdisciplinary VECTAMOD-PE project, your mission will be to develop and apply a computational model using CATHARE in order to:

- Simulate the impact of hypertension on BBB vascular walls and their long-term aging;

- Model the interactions between placental, cardiac and cerebral vascular compartments to understand how pressure fluctuation overloads propagate through the system and affect the cerebrovascular system;

- Model the stiffness of cerebral vessels and the transport of vasoconstrictive factors (secreted by the placenta) to the brain, depending on vessel diameter.

- Integrate experimental hemodynamic and MRI data into multiscale simulations to improve the understanding of cerebrovascular dysfunction associated with preeclampsia;

- Contribute to the development of predictive models linking pregnancy-related vascular stress to long-term cerebrovascular aging and disease risk.
