Joey earned his BSc in Physics from the Lebanese University in Lebanon. After receiving the ISFIN Excellence Scholarship, he joined the MSc program in Nuclear Fusion at Aix-Marseille University in France, graduating with cum laude honors. During his MSc, he worked at CEA Cadarache on the post-mortem analysis of tungsten ITER-like divertor plasma-facing components from the WEST tokamak. He also worked on deuterium retention in tungsten for divertor applications at DIFFER and on negative-ion surface production for neutral beam injection systems at PIIM.
Joey leads experiments on the DIONISOS linear plasma device focused on the dynamics of deuterium retention in boron layers on tungsten, the response of plasma-facing components to simultaneous plasma exposure and radiation damage, and the suppression of post-exposure deuterium outgassing caused by radiation-induced trapping. He also co-leads experiments on tungsten–SiC composites and their behavior under plasma exposure and radiation damage.
In parallel, Joey co-leads the development of new operating scenarios for DIONISOS, including efforts to access low-power helicon-mode regimes. He is also responsible for the maintenance, modification, and ongoing upgrade of the DIONISOS device at the PSFC.
