## 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.

## 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)
