Dr. Pradeep Kodimana Ramakrishnan is a postdoctoral researcher in the group of Prof. Gerd Bacher at the University of Duisburg-Essen, Germany since 2021. He obtained his integrated B.Sc., B.Ed., and M.Sc. in physics from the Regional Institute of Education, University of Mysore in 2014. He then received his Ph.D. in 2021, under the supervision of Prof. Ranjani Viswanatha, at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru. Dr. Ramakrishnan’s doctoral work focuses on the design of quantum dots for optoelectronic applications.
Dr. Ramakrishnan received a fellowship under the Walter-Benjamin Program from the German Research Foundation. His research grant focuses on magneto-optical spectroscopy of single perovskite nanocrystals. He has published several research articles in reputed international journals. He is the winner of Gandhian Young Technological Innovation Awards (GYTI 2020) in the field of nanoscience and engineering. He qualified the GATE examination 2015, with an all-India rank of 74, and secured first rank in the country in the national entrance examination conducted by NCERT in 2008. His other scientific recognitions include the “Best ePoster Content and Discussion” award at the 2020 online conference Light Emission in Organic and Hybrid materials (LightEm) organized by nanoGe, and another best poster award at an In-House symposium 2018, JNCASR. He is also a winner of the Sony World Photography Awards, 2023.
Inorganic lead halide perovskite nanocrystals are in high favor among recent energy materials. However, the necessary inclusion of lead, a toxic element, raises a critical concern for future commercial development. Dr. Ramakrishnan is addressing this issue during his Fulbright-Nehru Postdoctoral Research fellowship. He is designing and synthesizing doped lead-free double perovskites and studying their spin dynamics using ultrafast magneto-optical spectroscopy. This project provides a promising avenue for lead free perovskite nanocrystals for use in high performance photophysical applications.
