Work Experience

Data Scientist at Qwant (Nice, France) (2019 - now)

I am a data scientist engineer at Qwant . As a member of the team "Search", our goal is to improve the quality of the results delivered by www.qwant.com using Learning To Rank algorithms.

Post-Doc Researcher Universitat Pompeu Fabra (Barcelona, Spain) (2018 - 2019)

I did my postdoc at Universitat Pompeu Fabra in Barcelona (Spain) in the AI-ML team in Reinforcement Learning. I was involved in the European Project Dynamically Evolving Long-Term Autonomy (DELTA).

We applied (Hierarchical) Reinforcement Learning to optimize the electrical consumption of a smartgrid. We worked on a microgrid simulator developed by Montefiore research unit in Liège (Belgium).

Web development consulting project (2018)

I developed this webpage for dentists.

PhD in Applied Mathematics (PDE, Control theory and Numerical Analysis) Université Aix-Marseille (Marseille, France) (2015 - 2018)

I finished my PhD in 2018 at Aix-Marseille Université in Mathematics in Control Theory of Partial Differential Equations. I studied control properties of continuous and discretized Systems of Parabolic Differential Equations (PDE) (for instance, the heat equation \(\partial_t f -\Delta f = 0\) is a Parabolic PDE) and continuous Degenerated Parabolic Equations (More precisely, Grushin's Equation \(\partial_t f - \partial_{xx} f - |x|^{2 \gamma} \partial_{yy} f= 0 \)) . The spectral properties of Sturm-Liouville Differential Equations were crucial in the analysis. Find my thesis here.

See the introduction of my PhD for a detailed presentation.

Software Engineer Internship - Atos Wordline (2011)

We developed the following web application using HTML, CSS, Tapestry, Javascript and PHP.

Check my CV for more info.

Some Projects

Research in Maths, February 2020

Have a look at our article with Franck Boyer and Morgan Morancey : Analysis of the null-controllability of degenerate parabolic systems of Grushin type via the moments method.

Reinforcement Learning, 2018-2019

I did 1 year of postdoc in Reinforcement Learning within the DELTA European project where I use the microgridRL environment developed by the Montefiore Institute ULg.
I also applied our ideas on Atari Games environments and more specifically on the hard exploration game Montezuma's Revenge.

Numerical Simulation (from my PhD)

This represents the evolution of the heat of a 2D object, with a boundary control

Other (fancy) Projects 🤓 🎮

2kPlus Challenge !
Maxime Euziere and I participated to the 2kPlus Challenge. We finished 6th out of 20 participants with a demake of the famous flash game SHIFT (if you don't know Shift, look at this video)

Try out our shift demake written is JS in only 2ko ! (GitHub repo here)
