Sabuj Chandra Sutradhar, Ph.D., is a researcher specializing in advanced functional materials for energy, environmental, and biomedical applications. He earned his Ph.D. in Applied Chemistry from South Korea in 2019 after completing his B.Sc. (Hons.) and M.S. degrees in Chemistry at Shahjalal University of Science and Technology, Bangladesh. Since then, he has accumulated research and industrial experience across academia, national research laboratories, and the chemical industry. His professional career includes positions as a Senior Researcher in the chemical industry, Research Professor in a nanobiomedical research laboratory, and Postdoctoral Researcher in South Korea. Throughout these appointments, he has conducted research on electrochemical energy-storage systems, polymeric and nanostructured materials, fuel cells, biomaterials, and functional hydrogels. He has published more than 30 peer-reviewed articles and is the inventor of several Korean patents. Dr. Sutradhar's research interests encompass gel polymer electrolytes, stimuli-responsive hydrogels, lithium-ion batteries, sodium-ion batteries, supercapacitors, fuel cells, conductive polymers, nanomaterials, drug-delivery systems, and multifunctional biomaterials. His work emphasizes the rational design of advanced materials and their translation into practical technologies for sustainable energy storage, environmental remediation, and biomedical engineering.
