About Me

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