Research Interests

The advances in computer technology have now made it possible to simulate the atomic details in molecular and solid state systems. Our main interest is on the applications of computational and theoretical chemistry methods to study chemical reactions. We have our own in-house high performance computing facilities, made of PC clusters linked by high-speed network. Typical systems studied include ionic clusters, which are the prototype for understanding the detailed solvation interactions; carbon nanotubes, which are an important class of nano materials; and silicon surfaces, which are the most important material in semiconductor industry.
