Research Professor | Yeungnam University | South Korea
Dr. Dhananjaya Merum is an accomplished materials physicist and nanotechnology researcher from India, specializing in energy storage and conversion systems. He earned his Ph.D. in Physics from Sri Venkateswara University, Tirupati (2019) with a dissertation titled “Studies on Bulk and Thin Film Vanadium Oxide Nanostructured Electrodes for Energy Storage Applications.” He further advanced his research expertise as a Post-Doctoral Fellow (2021–2022) and currently serves as an Assistant Professor (2022–present) at Yeungnam University, Republic of Korea. His academic journey also includes an M.Sc. in Physics (2012) and a B.Ed. in Physical Sciences and Mathematics (2014) from Acharya Nagarjuna University, along with a B.Sc. in M.P.E. (2010) from Sri Venkateswara University. With over a decade of research experience, Dr. Merum has worked extensively on nanostructured and thin-film metal oxides (such as V₂O₅, MoO₃, Li₄Ti₅O₁₂, and BaSnO₃) for supercapacitors, batteries, and supercapattery applications using diverse synthesis methods including hydrothermal, sol–gel, sputtering, and evaporation techniques. His research interests span nanomaterials, aqueous batteries, supercapacitors, catalysis, and gas/chemical sensors. Dr. Merum possesses exceptional research and analytical skills, being proficient in material characterization techniques such as XRD, FTIR, Raman spectroscopy, FE-SEM with EDS, UV-Vis-NIR spectroscopy, and electrochemical analysis. He has independently operated and maintained advanced instruments including Raman spectrometers, TG-DTA analyzers, and electrochemical analyzers. His achievements include qualifying the APSET (2012), receiving the UGC-RGNF JRF and SRF fellowships (2016–2019), and being honored with the InSc Research Excellence Award (2020). He also holds a UK Design Patent (2023) and has authored 46 research papers in reputed international journals, including ACS Applied Materials & Interfaces and Journal of Materials Chemistry A. Dr. Merum’s dedication to innovation and academic mentorship underscores his commitment to advancing sustainable materials for next-generation energy technologies.
