About

A bit about me

I'm a graduate student at the MIT Master of Business Analytics, Operations Research Center, where I work on machine learning and analytics problems that sit close to real operational decisions: assembly lines, wildfire crews, construction schedules, and financial documents.

Before MIT, I studied engineering at CentraleSupélec in France, and worked as a data scientist intern across manufacturing, luxury goods, and investment banking.
