About us

Our group is involved in exploring fundamental aspects of density-functional theory, which is the most widely used theory of electronic structure of materials.

I am also interested in exploring new and different ways of teaching physics at all levels and look for ways of making learning of physics exciting without sacrificing its rigour.
