Research and teaching activities

I previously worked as a temporary lecturer and research assistant in Paul Sabatier University, Toulouse, in France. I did a PhD in the SEPIA team at IRIT, a computer science laboratory in Toulouse. My main research topic was the use of on-site intermittent renewable energy sources (such as photovoltaic panels or wind turbines) in medium-scale data centers. Although I am not currently working in research area, my publications are still listed bellow and you can access my PhD thesis.

Why a .cafe TLD?

Because coffee isn’t as dangerous as we tend to believe. And because coffee is cool (especially if you understand french)1:

Research publications

You can retrieve my PhD thesis (in english) from the official french website or directly from here. The slides of my defense are also available here.
