Dr. Vasiliev's areas of expertise include solid state physics and computational materials science. His research focuses on theoretical studies of complex nanoscale systems. Examples of such systems include atomic clusters and nanocrystals, nanotubes & nanowires, structural defects in crystals, surfaces & interfaces, as well as glasses and amorphous materials. Vasiliev is also working on the development of novel theoretical methods for predicting structural, electronic and optical properties of complex nanomaterials. His calculations employ a wide range of computational techniques with the emphasis on ab initio methods based on density-functional theory.
