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.
