Stéphan PLASSART

About me

Stéphan Plassart is an Associate Professor (Maître de Conférences) in computer science at University Savoie Mont-Blanc at the Listic laboratory, France. Before that, he spent three years as a postdoc researcher in the LCA2 team of Prof. Jean-Yves Le Boudec at EPFL in Lausanne, Switzerland. He hold an engineer's degree (equiv. Master of Science in Engineering) from Grenoble-INP ENSIMAG and a PhD from Université Grenoble Alpes, France, entitled “online energy optimization on real-time system”. This Phd was jointly done at LIG and at Inria Grenoble under the supervision of Bruno Gaujal and Alain Girault. His research interests include energy optimization, network calculus for Time-Sensitive Network (TSN), Markov decision process, learning, energy-aware distributed system and real-time systems.
