Professional Activities & Interests / Biographical Information
My main current interest is to understand fundamental properties of nanostructured materials using advanced numerical techniques. My research has focussed on development and application of numerical techniques for structural, electronic, transport and optical properties of surfaces, low-dimensional systems and nanostructures. Computer simulations performed in my group addressed self-assembly and physical properties of fullerenes, nanotubes, nanowires, polymers, ferrofluids, metallic and magnetic clusters.
Many of our calculations were and are being performed on cutting edge supercomputers, such as the Earth Simulator in Yokohama, Japan. This 40 TFlop massively parallel vector supercomputer was built at a cost of 500 million dollars and requires an annual maintenance fee of 50 million dollars. Substantial computational resources of typically several months CPU time on a large fraction of the vector processors have been made available by JAMSTEC and RIST in Japan for a collaborative effort to understand the stability of electronic nanostructured devices subject to electronic excitations and to study the mechanical stability of novel materials.
