Summary

my Research focuses on applying high-performance computing, Physics, computational Physics, condensed matter Physics and experiments to understand at atomic level the behavior and the properties of different materials ranging from simple metallic components to more complex materials such as multi-components metallic systems and glasses (silica, silicon, oxide glasses, bulk metallic glasses, amorphous materials, borosilicate glasses, nuclear glasses, ...). the topics of interest include, but not limited to, the following: simulation of static and dynamical properties of amorphous and disordered materials, liquids, glasses and multi-component metallic systems, bulk metallic glasses, melting, crystallization and solid-liquid interfaces on metallic materials; phase transitions in condensed materials (liquid-glass transition); solid-solid interfaces, inter-diffusion, diffusion mechanism in super-cooled and glassy materials, effect of mechanical shear deformations on the properties of amorphous and complex materials; structural defects; structure of the glasses used for nuclear waste storage; he and water diffusion in nuclear glasses, irradiation effects ... the computer simulation methods used to develop my scientific projects are: monte carlo (mc) and classical molecular dynamics (MD) Simulations. in the near future i would like to apply continuum modeling and first principle Simulations to study the properties of complex materials.
