Dr. Tirtha Raj Acharya is a Postdoctoral Research Fellow at the GSK Carbon Neutral Laboratories for Sustainable Chemistry, School of Chemistry, University of Nottingham, United Kingdom. He specializes in cold (non-thermal) plasma-driven chemical processes, with a strong emphasis on sustainable environmental and energy applications, including volatile organic compound (VOC) removal, nitrogen fixation, CO2 conversion, and plasma-catalytic systems. He obtained his Ph.D. in Plasma Physics from Kwangwoon University, Seoul, South Korea, where his research focused on non-thermal atmospheric pressure plasma, plasma diagnostics, plasma–material interactions, and environmental remediation technologies.

His current research integrates experimental plasma physics with chemical engineering and materials science to develop innovative and sustainable plasma-enabled solutions. At the University of Nottingham, he contributed to cutting-edge research under the EPSRC Prosperity Partnership funded with Lubrizol Ltd., Hazelwood, Derby, UK, advancing low-carbon chemical processes and energy-efficient molecular transformations. Dr. Acharya has published extensively in more than 50 high-impact international journal articles, contributing to diverse areas of non-thermal plasma science and its applications, including plasma catalysis, environmental remediation, nanomaterial synthesis, plasma medicine, and energy conversion technologies. His interdisciplinary research aims to advance plasma-based sustainable technologies for environmental protection, clean energy production, and biomedical applications. He also serves as a peer reviewer for over 100 scientific manuscripts across leading international journals. In addition, he holds active editorial responsibilities as Guest Editor and Topic Editor for several international journals, including Springer Nature, MDPI, Frontiers, and JoVE.
