About my research

I work on synthesizing near-infrared light emitting perovskites for optoelectronic applications.

I recently completed my PhD from Prof. Angshuman Nag's lab at the Indian Institute of Science Education and Research (IISER) Pune. My doctoral thesis focused on synthesizing near-infrared (NIR) light emitting perovskites for optoelectronic applications. My research interests span colloidal nanocrystal synthesis, material characterization, and optoelectronic device fabrication.
