Multiscale modeling of nanostructures; crystal defects; phonons in nanostructures; modeling of mechanical properties of semiconductors and solid-state devices. Special interest: Lattice, continuum, and multiscale Green's functions (Originated Green's function method for lattice statics).
Responsibilities at NIST
Project Leader of the MRD projects on Green's function methods for nanomaterials (quantum dots and nanowires); Project Leader of the SIMA (Systems Integrated Manufacturing Agency) project on library of Green's functions; Project Leader of the project on "Modeling and characterization of combinatorial libraries"; ATP (Advanced Technology Program) project on bridging the length scales.
Created and led a group on Green's functions at the CTCMS (Center of Theoretical and Computational Materials Science). Formed and led a consortium of researchers and teachers from several universities and industries. Helped setting up a digital library of Green's functions in a project sponsored by NSF in association with Kent State University.
