Our group is primarily involved in the mathematical and computational modeling of mechanical properties of solids. These studies involve nanostructured and bulk crystalline metals, beside the glassy metallic alloys. The scope of modeling encompasses various scales of length and time. The computational strategies include molecular dynamics, stochastic modeling, phase filed simulations, cellular automata, and various aspects of material informatics. Currently, the major themes of investigations are:
1. Modeling and computer simulations of the structure and behavior of crystal dislocations
2. Materials informatics
3. Atomistic simulations of deformation of metallic glasses
4. Evolution of dislocation microstructure in deforming nanocrystalline metals
