Dr. Anuja Arun Yadav is a JSPS Fellow at the Faculty of Pure and Applied Physics, University of Tsukuba, Japan. Her research focuses on the synthesis of advanced nanomaterials for energy storage and photocatalytic applications, with emphasis on supercapacitors, batteries, and photo- and electrocatalytic energy conversion systems. She has extensive experience in material design for self-charging supercapacitors and in integrating solar-energy harvesting with electrochemical storage for sustainable, off-grid technologies. Before joining the University of Tsukuba, Dr. Yadav worked as a Research professor at Yeungnam University, Republic of Korea, and as a Researcher at the University of Tokyo. She is also a recipient of the JSPS Fellowship (Japan) and the SERB National Postdoctoral Fellowship (India). She has published more than 70 peer-reviewed papers, several book chapters, and a monograph, with over 4300 citations (h-index 41). Recognized among the World’s Top 2% Most Influential Scientists (2022–2024) by Stanford University and Elsevier, her current research targets hybrid photo-rechargeable driven supercapacitors for next-generation sustainable energy systems.
