Welcome to my personal website!
 

I'm a doctoral researcher working at the NanoEngineering Lab of the University of Illinois at Chicago. My research pertains to developing electrodes and polymer electrolytes for rechargeable batteries and evaluating their performance in lab scale. For my Ph.D. thesis, I focus 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 coming to UIC, I worked at the Nanoscience and Energy Materials 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.
