Prof. Nagarajan joined the Central University of Tamil Nadu in 2012, and currently holds the position of Head of the Department of Chemistry. He was the first faculty appointed to the department and has served as the founding Head from 2013 to 2019. He has contributed significantly to the university, taking on key roles such as the Dean of the School of Basic and Applied Sciences from 2016 to 2021, Dean of Students’ Welfare from 2017 to 2021, the Controller of Examinations (i/c) from 2021 to 2023, and Presently, he serves as the Dean of Academics at CUTN. His academic journey includes obtaining a BSc (Chemistry) from Pioneer Kumaraswamy College, Nagercoil, and completing his MSc (Organic Chemistry) and PhD (Chemistry) from Annamalai University. Following his graduation, he joined Annamalai University as a faculty member. During his academic career, he gained international exposure as a Postdoctoral Fellow at the Nanoscience group of CEMES-CNRS in Toulouse, France, and as a Guest researcher at the International Center for Materials Nano-architectonics (MANA), NIMS, Tsukuba, Japan.
His exemplary contributions were recognized with the prestigious BOYSCAST Fellowship, awarded by the Ministry of Science and Technology, Govt. of India. He also received the Young Scientist Fellowship from the Tamil Nadu State Council for Science and Technology, and the CSIR Research Fellowship, New Delhi. His achievements also include becoming a Fellow of the Royal Society of Chemistry, the Indian Chemical Society and the Fellow of the Academy of Sciences, Chennai. With an impressive scholarly record over the course of his career, he has successfully supervised 15 PhD scholars, 22 MPhil candidates, and three Postdoctoral Scholars. In recognition of his research endeavors, Prof Nagarajan secured a research grant totaling Rs. 160 Lakhs from prestigious funding bodies such as DST, CSIR, UGC, and industry.
Organic Electronics is a budding interdisciplinary research area focusing on technologies that rely on organic semiconductors instead of traditional inorganic ones. Organic electronics will help us to address the crucial problems of modern society. This field results in low-cost, lightweight, flexible, wearable technologies, energy-efficient lighting, efficient memory devices, and molecular sensors.
Virtually unlimited possibilities of synthetic organic chemistry and compatibility with inexpensive solution-based fabrication techniques make organic semiconductors an extremely viable novel technology of the future.
Research in our group focuses on developing new materials for organic electronics and understanding how molecular structure alters the properties of such materials. For this purpose, we work on molecular design, synthesis, characterization techniques, photophysical studies, computational studies, device fabrication, and characterizations to advance the field of organic electronics and contribute to the development of efficient and sustainable electronic devices for information processing.
