SHORT BIO

I am a junior researcher (chargé de recherche) at The French National Centre for Scientific Research appointed at INSA Lyon. Previously, I was a Postdoctoral Researcher at EPFL, Lausanne working with Prof. Rachid Guerraoui and Prof. François Taïani on Federated Learning. I obtained my PhD from Toulouse University under the supervision of Prof. Daniel Hagimont and Prof. Alain Tchana. In the context of my research, I have also collaborated with other research partners from tech companies (e.g., Facebook, IBM, Huawei) or academia (e.g., ETH Zurich, George Washington University, Virginia Tech).

RESEARCH INTERESTS:

  • Robust Federated Learning

  • Mobile TEEs (e.g. ARM TrustZone)
