I have very good memories of the PCS master. I did my PhD in computer science at complexnetworks.fr under the supervision of Prof. Jean-Loup Guillaume and Prof. Benedicte Le Grand. Since september 2015, I am a a postdoc at Telecom ParisTech under the supervision of Prof. Mauro Sozio. My research interests revolve around the study of very large real-world graphs, machine learning and big data.
