Abbas M.K.AL-Rjoub obtained his Bachelor’s in physics/mathematics from the University of Birzeit, Palestine, in 2007. He completed his first Master’s in applied mathematics at the same university. In 2012, he completed another Master’s in physics at the University of Sussex, UK. In 2019, he received his PhD in physics (MAP-fis, joint doctoral program in Physics of Universidade do Minho, Universidade de Aveiro, and Universidade do Porto). In 2019-2022, he worked as a postdoctoral researcher at the University of Coimbra, CEMMPRE—Centre for Mechanical Engineering, Materials, and Processes. In 2023, he obtained a one-year research position in Physics Engineering at Polytechnique Montréal, Montreal, Canada. Currently, he is a postdoctoral researcher at Mobility GT (Marie Skłodowska-Curie Actions (MSCA)): Surfaces and interfaces for sustainable green mobility, a joint program between the Laboratory for Tribology and Interface Nanotechnology (TINT) of the University of Ljubljana (Slovenia), University of Leeds (UK), Luleå University of Technology (Sweden), and University of Coimbra (Portugal). His research focuses on the Optics of Thin Films, Magnetron Sputtering, Thin Film Deposition, Oxidation and Wear Resistance, Corrosion, Nanoparticles, Nanomaterials, Simulation, Material Characterization, Hard Coatings, Dry Machining, Surface Engineering and Tribology, Friction, Self-lubricant Coating, Selective Coatings for Solar Thermal Absorptance, and Thermal Barrier Coating Systems.
