Cloud Computing Researcher
Introduction
I am interested in the environmental footprint of cloud computing and how system engineering can reduce it, developing methods that help providers accommodate diverse usage at scale. I currently focus on sharing mechanisms through orchestration and oversubscription.

Bio
I am a postdoctoral fellow at ÉTS Montréal (Canada), hosted at the OVHcloud Montréal offices as part of an ongoing collaboration. I hold a PhD in Computer Science from the University of Lille (France), realized within Spirals and Stack teams from Inria (2021-2024). I received my Computer Science engineering degree in 2021 from Paris XII University (France), giving master's degree. Prior to the PhD, I spent three years working on the Mainframe security ecosystem.
