I recently completed my PhD viva-voce examination in Department of Physics and Nanotechnology, SRM Institute of Science and Technology, Kattankalathur, Tamil Nadu, India and pronounced as Dr. My research interest includes toxic free catalytic materials (Ag, Cu based ternary metal sulfides) as Pt-free counter electrodes for third generation solar cell applications. I had published 4 experimental research works as a first author and 6 research works as a co-author in international journals.
