The broad areas of Research are Simulation of Dislocations and Epitaxial systems by Finite Element Method, Study of complex intermetallics. Finite Element Method (FEM) is not only a powerful tool for engineering analyses, but also for understanding the fundamental material behavior at the nano scale. In fact 'new phenomenon' and 'new materials' can be discovered using FEM simulations. This becomes possible because continuum behavior can be retrieved at the length scale of even a few lattice spacing. Various structures and defects in crystals can be simulated and associated processes can be understood using FEM. These include:
- Simulation of dislocations, epitaxial films, twins, grain boundaries, precipitates etc.
- Study interactions between these defects
- Formation of interfacial misfit dislocations in epitaxial thin films
- Precipitation and coherent to semi-coherent transition of precipitates

Our current interest lies in using differential geometry and PDE theory to study irreversible dynamics of defects in solids. In particular, we are looking at the following problems: 1) Dynamics of incoherent boundaries within solids (e.g. grain boundaries), 2) Classification of defects in solids on the basis of geometry and group theory, 3) Surface growth in biological systems.

Our research team is engaged in both computational and experimental study of incompressible fluid flow and heat transfer for various applications. For computations, both DNS (direct numerical simulation) and turbulence modeling (RANS: Reynolds Averaged Navier-Stokes, both steady as well as unsteady, LES: Large Eddy Simulations) are carried out depending on the value of Reynolds number. In experiments, Hot-wire anemometry (HWA), Laser Doppler Velocimetry (LDV), Particle Image Velocimetry (PIV), Laser Induced Fluorescence (LIF) and Infrared Thermography techniques are used to characterize the flow and heat transfer. The following pictures shows one of the images of a controlled circular jet at Re=2,000 simulated using DNS technique.
