Teaching activities:
  • Electrochemistry (basics; interfaces; electrocatalysis; corrosion; materials)
  • Chemistry (organic, physical and analytical)
Research interests:
  • Interfacial electrochemistry: catalyst layer study in conventional three-electrode (RDE) or in gas diffusion electrode (GDE) devices.
  • Electrocatalysis at solid-liquid interfaces: oxygen reduction and evolution reaction (ORR and OER) and hydrogen evolution reaction HER in acidic and alkaline environements.
  • Durability of electrodes and electrocatalysts for hydrogen fuel cell and water electrolyser: degradation mechanisms study, establishing structure-activity-stability relationship.

Education:

  • Since October 2023: Associate Researcher at CNRS
  • 2022 - 2023: Postdoctoral researcher at HIERN, Erlangen, Germany
  • 2018 - 2022: Postdoctoral researcher at LEPMI, Grenoble, France
  • 2014 - 2017: PhD in electrocatalysis at IC2MP, Poitiers, France
