We work on different aspects of diffusion-controlled microstructural evolution in complex multicomponent materials which are related to various high temperature physical and mechanical properties of materials.

Recently, we solved the unsolved by developing new experimental methods in multicomponent diffusion, which remove the stringent mathematical and experimental obstacles based on Onsager formalism after nine decades. The single-phase high entropy alloys and other multicomponent concentrated alloys provide platforms to establish the newly developed methods by correlating diffusion rates of components with microstructural and compositional evolution.

We work extensively on coatings for Ni-base single crystal superalloys used in jet engines and land (power sector) based gas turbines, various aspects of material systems used in flip-chip bonding of micro-electronic component, growth of A15 intermetallic superconductors for the use in several advance technologies (ITER project, high luminosity in large hadron collider at CERN).
