Biography
Reshma P. R. is a Postdoctoral Research Associate at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad. Her research focuses on the development and application of low-dimensional materials, particularly 2D transition metal dichalcogenides and metal oxides, for advanced functional applications including microwave absorption, catalysis, sensing, and energy storage. She obtained her Ph.D. in Physical Sciences from the Homi Bhabha National Institute (HBNI), Mumbai, with research carried out at the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam. Her doctoral work pioneered the synthesis of bilayer 2D V₂O₅ and reported, for the first time, vibrational and electronic decoupling in this system. She further demonstrated its potential in Zn-ion and Zn/Li hybrid batteries, as well as in photocatalytic and gas sensing applications. Her expertise spans the controlled synthesis of 2D transition metal dichalcogenides using techniques such as chemical vapor deposition, along with advanced nanoscale characterization methods including AFM, TERS, and low-temperature Raman/photoluminescence spectroscopy. Her work also explores light–matter interactions at the nanoscale, defect engineering, and structure–property correlations in functional materials. Reshma has authored multiple peer-reviewed publications in reputed international journals, contributing significantly to the understanding and application of 2D vanadium-based systems and transition metal dichalcogenides.
