My research interest is focused on interaction of light and matter to study the optical and electrical properties of mostly semiconductor materials in near-field and far-field regimes. In broad context, I focus on the area of “confinement of the light at nano-scale regime”. Optical and electrical properties of subsurface crystallographic defects, plasmonic nano-structures, interacting quantum dots, surface properties, nonlinear optical characterization of thin films.... are some of the area that I have been active.
