Currently I am a PhD student at Graphene Labs- Italian Institute of Technology and Department of Physics, University of Genova. My research focuses on developing novel strategies combining graphene and gold plasmonic fractal nanoantennas for enhanced light-matter interaction. My areas of expertise include Graphene, Plasmonics, Micro/Nanofabrication, Nanoelectronics, Nanophotonics and Optoelectronics.

I have obtained my Master degree (5 years integrated MSc in Photonics) from International School of Photonics, Cochin University of Science and Technology; with a highly interdisciplinary curriculum combining Material science, Optics, Quantum mechanics, Nano and bio-photonics, semiconductor electronics etc.
