PROFILE

I am currently working as an Assistant Professor in the Department of Applied Physics at Delhi Technological University, Delhi.  My research focuses on synthesizing metal oxide nanostructures and nanocomposites for applications in gas sensing, dye degradation, and as a photoanodes for green hydrogen generation. I also work on fabricating 2D hybrid metal oxide reinforced PVDF flexible films using solution casting and spin coating with advanced dielectric, optoelectronic and thermoelectric characteristics for energy harvesting and storage towards flexible self-powered devices.
