Welcome to my personal website!

I am a materials researcher and a recent Ph.D. graduate from the University of Illinois Chicago. My research pertains to developing electrode materials and solid electrolytes for rechargeable batteries and evaluating their performance in lab scale. For my Ph.D. thesis carried out at the NanoEngineering Lab, I worked on developing composite polymer electrolytes for lithium-metal and multivalent-ion batteries -- a class of batteries that can potentially be more powerful, lighter, and safer than its present-day lithium-ion counterparts.

Before my Ph.D., I worked at the Nanomaterials and Energy Devices Lab of the Indian Institute of Science Education and Research, Thiruvananthapuram, where I completed my Master's thesis on nanostructured electrode materials for lithium-ion and sodium-ion batteries.
