Dr. Rishi Ranjan Kumar

Dr. Rishi Ranjan Kumar currently serves as an Assistant Professor in Physics Department at School of Basic and Applied Science. He obtained his Ph.D. degree in July 2022 from Department of Materials Science and Engineering, National Tsing Hua University, Taiwan. He is a highly motivated and progress focused researcher in the field of materials synthesis, characterization, and analysis. His research activities during Ph.D. focussed on developing highly sensitive, economical, defect-rich, ultrasensitive, and light-activated nanomaterials/composites for the detection of toxic gases such as NO2, NO, NH3 and O3.

He was awarded the prestigious postdoctoral fellowship by the National Science and Technology, Taiwan, and subsequently joined National Yang Ming Chiao Tung University, Taiwan, where he dedicated 10 months (November 2022 – September 2023) to his research endeavors. During this tenure, his focus centered on the development of advanced multilayered polymer devices designed for ammonia sensing applications.

He did his masters from Jamia Millia Islamia and University of Delhi, India where he gained experience in the thin film deposition processes using physical vapor deposition techniques which includes thermal evaporation, sputtering, e-gun evaporation, atmospheric pressure chemical vapor deposition (APCVD) and some chemical routes techniques such as hydrothermal and seed-assisted growth.
