Research background
PhD thesis in physics on high-entropy nanoalloys studied by advanced transmission electron microscopy (in-situ and operando). Study of their thermodynamic stability, their reactivity under gaseous atmosphere (O2; H2), and their catalytic activity towards the CO2 reduction reaction.
Academic background
2017-2019 – Preparatory studies in industrial chemistry in Tunisia – National Institute of Applied Sciences and Technology (INSAT) of the University of Carthage.
2019-2022 – Engineering degree in materials and nanotechnologies in France – Denis Diderot Engineering School (EIDD) of the Université Paris Cité.
