adress: 102 Avenue de Paris, Massy, France.



I am R&D PhD-engineer at Safran Electronics & Defense.


I finished my thesis in 2018 at Université Paris-Sud, in collaboration with Safran Electronics & Defense, Inria Lille-Nord Europe and the Laboratoire des Signaux et Systèmes.


Here is a link to my CV.


Research interests

Robust control, parametric control, parameter estimation, gap-metric, polynomial system solving, real algebraic geometry, robotics, navigation.

Quick presentation

During my thesis, I worked on designing robust control laws to stabilize families of models of a system or, in other words, sets of models depicted by model parameters. The final objective is to compute robust control laws depending on these parameters which stabilize any model of this set. We call this approach parametric robust control.

In my thesis, I show how to use modern techniques of symbolic computation dedicated to the solving of polynomial systems of equations to design these new parametric control laws. Then, using this methodology, one can obtain new useful information for the design of a robust control law.

I invite you to see the Publications section for more details.

Nowadays, as a R&D engineer at Safran Electronics & Defense, my research activities mainly concern the extension of my thesis results to practical applications, such as robotics or inertial stabilization. In this perspective, I often mentor some students on innovative technical subjects in this field of research.
