Research Interest

  • My research work mainly focuses on computational materials science, that is, I use electronic structure methods as a tool to investigate the electronic properties of novel functional materials. My research activities directed towards the design and development of novel molecules and materials for organic electronic devices. Besides, I am also studying the nature of weak interactions in prototype molecular systems to determine their strength.
