Dr. Roopali Prajapati

Assistant Professor, Chemistry and Biochemistry


She have completed B.Sc. and M.Sc. (Physical Chemistry) from Ramjas College, Delhi University. Then,  joined the research group of Prof. Tushar Kanti Mukherjee in IIT Indore. Her PhD 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. Furthermore,  also explored the effect of various microheterogeneous environments such as surfactants, polymers, and DNA on the efficiency of resonance excitation energy transfer. After completing Ph.D. from IIT Indore, she joined as Postdoctoral fellow in Prof. Sameer Sapras research group at IIT Delhi where she have worked on the development of single-molecule photoluminescence set-up to analyze different quantum dots and perovskite nanomaterials.
