Since 2012, I am a permanent research scientist at CNRS (Centre National de la Recherche Scientifique) in the Magellan team at IRISA in Rennes, France.

Formerly, I was a postdoctoral researcher working at the Department of Electrical and Electronic Engineering of the University of Melbourne, in Australia. I obtained my PhD from ENS de Lyon in France in September 2011.

My main research topics are energy-efficiency in distributed systems, cloud computing, networks, and smart grids.
