“To myself I seem to have been only like a boy playing on the seashore… whilst the great ocean of truth lay all undiscovered before me.” --- Isaac Newton 

At the Indian Institute of Technology Delhi's Optics and Photonics Centre, I am Arannya Ghosh, a research scholar supported by the DST-INSPIRE fellowship. The primary emphasis of my research at IIT Delhi's "Laser Optics and Nonlinear Photonics Laboratory" is the practical and theoretical validation of the impact of non-trivial and trivial topologies on a range of second- and third-order nonlinear optical effects. In recent days, our focus has been on developing "All-optical spintronic devices" that utilize nonlinear optical phenomena.
