RESEARCH
I am primarily interested in electronic transport and collective excitations in low-dimensional
condensed matter systems. In this regard, I have carried out investigation of dielectric response
properties of 2D and quasi-1D electron systems in a magnetic field. I have also studied electron
transport in various low-dimensional systems, such as two-dimensional electron gas (2DEG)
systems realized in semiconductor heterostructures and Dirac Fermion systems like graphene
silicene and topological insulators. Current interest is in topological properties of Dirac Fermion
systems and topological phase transitions occurring in these systems. More recently, I have been
interested in nonequilibrium dynamics in these systems.
