About me


Since June 2016, I work as Data Scientist at Homly You, a Saint-Gobain subsidiary.

As a mathematician by training, I love nothing more than to use figures (data!) to understand complex, challenging situations — and help others make sense of them.

Data management

    I still remember some German grammar, but sadly the only vocabulary I have left is pretty much useless (as, for instance, Meerschweinchen). I wouldn't mind having to learn it back, though.
    Same goes for Latin but I'm less hopeful, for obvious reasons.
