Dr. Esakki Karthik completed BSc and MSc in chemistry from Manonmanium Sundaranar University, Tamilnadu. Later he qualified CSIR-UGC-JRF examination, followed by completing a doctorate from CSIR-CECRI, Karaikudi under the guidance of Dr. K.L.N. Phani, during his doctorate program he completed an Indo-Australia (Monash University) joint project for developing water oxidation catalyst to generate hydrogen. His main interests are surface electrochemistry and the electrified interface. Later, he moved to IISER-Mohali, where he mainly worked in the area of waste to wealth generation for utilizing waste poly bags for useful applications and got a project from DST, the Indian government for developing a stable water oxidation catalyst. Then he was invited as a visiting professor to the University of Brescia, Brescia, Italy. Afterward, he joined in IISER-Thiruvananthapuram as a postdoctoral researcher for developing oxygen-based redox catalyst and electrochemistry of metal clusters. Next, he moved to the Hanyang University, Seoul, under Brain Korea-21 program, where he worked in electrochemical hydrogen generation and utilization of electronic wastes.

In August 2022, he joined the Research Institute of Sustainable Energy (RISE) under TCG CREST as a Research Scientist. Now, his interest is to achieve a sustainable society through developing fuel cell technology for energy storage, CO2 reduction for controlling green gas emissions, water electrolysis for hydrogen fuel generation, and electronic waste utilization for pollution-free society.
