Research

Work

I am working as a research engineer part of the Exa-MA project of the PEPR Numpex, especially working on discretization methods for Exascale simulations.

During my PhD, I worked on mathematical modeling, simulation and order reduction of ocular flows and their interactions. The models are simulated using the Feel++ library, to whose development I contribute.

I also took part in CEMRACS 2023 on the theme of «Scientific Machine Learning», and worked on a project to estimate interactions in microbial communities using neural networks. This project was proposed by Lorenzo Sala of INRAE, Jouy-en-Josas.
