SHORT BIO

I am a Postdoctoral Researcher at EPFL, Lausanne working with Prof. Rachid Guerraoui and Prof. François Taïani on distributed machine learning at the Edge. Previously, I obtained my PhD from Toulouse University under the supervision of Prof. Daniel Hagimont and Prof. Alain Tchana. While at Toulouse University, I focused on topics related to operating systems, virtualization systems, edge computing and energy efficiency in the cloud. During my PhD, I also collaborated with IBM, Huawei, ETH Zurich, George Washington University and Virginia Tech.
