Research Interests

Research in our group deals with the study and
design of advanced materials using computational modeling and simulation. Within
a parameter-free first-principles approach, we employ quantum mechanics and
statistical mechanics to study electronic structures, interatomic bonding and
microscopic kinetic processes in modern high-performance materials. Current
research directions include (i) theory of bulk and surface alloys, (ii) studies
of nanoscale self-assembly and ordered pattern formation on metal and
semiconductor surfaces, (iii) structure and growth kinetics of epitaxial
nanostructures, (iv) solid-state hydrides for reversible hydrogen storage, and
(iv) development of new computational algorithms for predicting crystal
structures and physical properties of complex materials. Our research is funded
by NSF, DOE, and SRC-MARCO.

Area of Thesis Guidance

Self-assembly, directed self-assembly, pattern formation, metal and
semiconductor heteroepitaxy, nanostructured materials, first-principles
calculations, phase diagrams and phase stability, ordering in alloys, dynamical
properties of solids, metal hydrides, complex hydrides, hydrogen storage,
thermoelectrics.
