Research Interests: 

To develop advanced theory, algorithms and numerically efficient codes to explain various properties, structure  and  behavior of  materials.

Recent interests involve :

      • Structural, Magnetic and Quantum Phase Transition in Intermetallics.
      • Understanding exotic phases of Superconductors and Topological Insulators.
      • Eect of variable relaxation time on thermoelectric properties of materials
      • Electronic and Optical properties of solar harvesting materials

Electronic Structure and Thermodynamics of Alloys :

      • Transition metals, Binary and Ternary Alloys.
      • Long-range, Partial and Short-Range Ordering in Alloys.

Vibrational properties of intermetallic and disordered materials :

      • Phonon dispersion, vibrational entropy, short-range ordering.

Response functions in materials with defects :

      • Electrical conductivity, Electronic and Lattice thermal conductivity
