PhD student in stochastic optimization for energy systems

Presentation

I work as a PhD student in a R&D company named Efficacity. Our aim is to support actors, from industry and public sector, where they can make a change for cities energy efficiency. I develop methods to optimize energy systems in real time in the presence of uncertainty. It requires stochastic optimization as well as models reduction/calibration technics and some probabilities/statistics. I apply these methods mainly to improve energy efficiency of subway stations and related assets. My advisor for my work in stochastic optimization is Jean Philippe Chancelier from CERMICS. Frédéric Bourquin from IFSTTAR is my advisor for the multi-physical models reduction/calibration.
