He held an Habilitation thesis (HDR) from University of Nantes in July 2018 in which he proposes dynamic reconfiguration of software architectures (in particular for "green Clouds"). He heads several national projects and serves on a number of conference program committees. His interests include Software engineering, Autonomic computing, Green computing and/or Cloud computing. Now, he investigates self-adaptive component-based applications for large-scale distributed systems supplied by renewable resources.
