About

My research primarily revolves around electrochemical energy storage technologies such as Li-ion, Na-ion batteries, and supercapacitors. Currently, my research activities are concentrated on advancing beyond lithium energy storage systems, with a specific focus on Na-ion batteries. I am particularly involved in the development of hard carbon anode materials derived from waste biomass.

Previously, I served as a Research Scientist at RIL, India, where I contributed to the development of next-generation cathode materials for both Li-ion and Na-ion batteries. Additionally, I was involved in the creation of hard carbon anodes for Na-ion batteries.

My doctoral studies, sponsored by DST, India through the INSPIRE Fellowship program, were conducted at AcSIR, CSIR-CECRI, India. During this time, I concentrated on the development of various TMO/graphene nanocomposite electrodes and high surface area porous carbon electrodes derived from biomass for supercapacitor applications. My doctoral thesis got AcSIR Best Ph.D. Thesis Awards in 2019. I hold a master’s degree in Nanoscience and Technology from Alagappa University, Tamil Nadu, India.
