I have obtained my 5 years integrated Master degree in Photonics from International School of Photonics, Cochin University of Science and Technology, India in 2014 which is an interdisciplinary course emphasizing on Nano technology, Laser technology, Spectroscopy, Optoelectronics, Fiber optics, Non-linear optics etc on the firm foundations of basic physics, mathematics, electronics and computer science. My master thesis (Macquarie university and Commonwealth Scientific and Industrial Research Organization, Sydney, Australia) involved fabrication and study of plasmonic dichroism in noble metals.

Currently I am a doctoral researcher in Graphene Labs, Italian Institute of Technology and Department of Physics, University of Genova, Italy. My current research project focuses on the fabrication of novel nanostructures in graphene, gold and hybrid systems and investigation of their electrical, optical and plasmonic properties. My areas of expertise include graphene and other 2-D materials (production and characterization), plasmonics, nano fabrication (Electron beam lithography), nano photonics and optoelectronics.
