Dr. Chetna Tewari received her M.Sc. in Organic Chemistry and her Ph.D. degree in Chemistry from Kumaun University (KU) Nainital in 2022. After completing her Ph.D., she joined the Korea Institute of Science and Technology, Republic of Korea as a visiting scientist, where she continues to work. Her research focuses on the bulk production of graphene nanosheets from solid waste plastic as well as other waste materials such as waste paper, tire waste, agriculture waste, and petroleum waste, along with exploring their various applications. In addition, she possesses expertise in the synthesis of graphene-based composites with other carbon materials, metal oxides, and polymers. Moreover, her research areas cover carbon nanomaterials, supercapacitors, polymer nanocomposites, water treatment, bio-imaging, sensing, energy, and waste upcycling. Recognizing her outstanding contributions, Dr. Tewari was honored with the prestigious Young Women Scientist Excellence Award for the years 2022-2023, as well as the Young Scientist Award, among others. In terms of her academic output, to date, Dr. Chetna Tewari has published more than 42 research papers in high-quality international journals, holds 11 national and 3 international patents, and has presented 18 papers at international and national conferences and symposiums.
