Dr. Roopali Sharma is currently working as Assistant Professor in the Department of Chemistry, School of Basic Sciences, Galgotias University since October 2023. She has more than 5.5 years of experience in teaching and industrial research. She completed B.Sc. and M.Sc. from Ramjas College, Delhi University followed by PhD from IIT Indore in 2018. Her research work was focused on understanding and unveiling the fundamental mechanism and dynamics of resonance excitation energy transfer from various photoexcited donors such as semiconductor quantum dots, carbon dots, and dyes to nearby metal nanoparticles and nanoclusters in the presence of various microheterogeneous environments such as surfactants, polymers, and DNA. After completing PhD from IIT Indore, she joined as Postdoctoral fellow in Prof. Sameer Sapra’s research group at IIT Delhi where she has worked on the development of single-molecule photoluminescence set-up to analyze different quantum dots and perovskite nanomaterials. She has also worked as Assistant Professor (Chemistry) in Sharda University for 3.5 years. Her industrial research experience as Lead Scientist (R&D) is related to the recovery of valuable elements from the spent Li-ion batteries via hydrometallurgy. She has published 10 research papers and 1 book chapter in reputed international journals.
