The elements in the periodic table and their combinations provide us with an incredible variety of materials and related physical phenomena. Our research is aimed towards unravelling the complex relationships between composition, structure and physical properties, using atomistic first-principles (ab initio) quantum-mechanical calculations. Recent material systems of interest include: two-dimensional layered materials, and transition-metal oxides and sulphides. We broadly focussed on predicting the structural, electronic and optical properties of materials and understanding the role of defects and dopants.

Ab initio calculations use the underlying laws of quantum-mechanics to explain material properties requiring only the atomic numbers and positions of atoms as input. The methods we use are based on density functional theory (DFT) and many-body perturbation theory (MBPT). These first-principles methods have, in the past, resulted in excellent quantitative agreement with experiment and have predicted material properties with good accuracy. Addressing the more complex materials science problems necessitates development of newer methodologies which can answer those questions. To this effect, we are also interested in developing new methods.
