I am currently a data scientist at Veolia Eau d'Ile-de-France solving problems related to the production and distribution of drinking water.

I have completed my PhD thesis in change-point detection and data analysis at Ifsttar / Grettia and Veolia Environnement Research & Innovation. This PhD work was done under the supervision of Patrice Aknin and Allou Samé from Ifsttar.

My research interests mainly involve industrial diagnosis, change-point detection, sequential hypothesis testing, segmentation of functional data, finite mixture models and EM-like algorithms in unsupervised and semi-supervised learning.

Thesis: Detection and classification of temporal CAN signatures to support maintenance of public transportation vehicle subsystems
