I am an assistant professor in the Department of Physics at the Indian Institute of Technology Roorkee and also a joint faculty member at the Center for Photonics and Quantum Communication Technology, IIT Roorkee.
Research Interest:
Light amplification in disordered amplifying structures, lasing in liquid crystal elastic materials and nanostructured thin film metamaterials.
Quantum optics, Photonic crystals, Topological photonics, metamaterial absorber, plasmonics and mesoscopic phenomena like Anderson localization.
Study of light interaction with microstructures using analysis tools like Transfer Matrix method, Finite Difference Time Domain method, Monte Carlo simulation, and COMSOL, etc.
Near field studies of passive and active nanostructured materials using Near Field Scanning Optical Microscope.
