Overview

I work on numerical simulation for atmospheric gas discharges in interaction with external flows, specifically corona discharges, with a strong interest in robust and fast numerical methods, particularly the so called stabilized finite element methods.

Projects

IPROP — Ionic Propulsion Systems for Atmospheric Applications

My research is part of the Horizon EIC Pathfinder project IPROP, which aims to develop propulsive technologies based on ionic wind generated by atmospheric plasma discharges. The project brings together researchers in fluid mechanics, plasma physics and numerical modelling to explore new propulsion concepts.

My contribution focuses on the numerical modelling of plasma–fluid interactions in the presence of external flow, by developing numerical solvers relying on the stabilized finite-element method.

These simulations are used to study the design and optimization of plasma-based propulsion devices and to better understand the multiphysics mechanisms governing ionic wind generation, as well as allowing practical and easy thruster design and testing to accurately estimate thrust, thrust-to-power ratio, and efficiency.

About Me

I was born in Lisbon, Portugal, and moved to Paris to study physics and mathematics. I moved to Toulouse after finishing my masters to pursue a PhD. I am very passionate about both physics and mathematics, which is why I studied in numerical methods for Partial Differential Equations, as they allow me to make use of and keep discovering complex mathematical tools, and then use them to study the physics of the fascinating phenomena that are atmospheric plasmas or fluid dynamics, as well as many others that I hope to one day study as well.

Aside from scientifical research, I enjoy learning about anything and everything, and spend most, if not all, of my free time reading and writting, mainly fiction but also philosophy, poetry or history.
