About Pierre

Polytechnic engineer and PhD in physics, I work on a wide variety of projects involving in-depth technical content. I can provide scientific advice and develop mathematical and physical models to solve complex problems.
My previous achievements include the development and implementation of an electric vehicle consumption model, the analysis and optimization of working time on a construction site, the applications of natural language processing in cybersecurity, and the development of ice cream processes and recipes that allow for a long shelf life without the use of chemical stabilizers.
Thanks to my strong background in scientific research, I am able to apply cutting-edge knowledge and technologies to solve various practical problems.
