Myself, Dr. Subhra Das, Assistant Professor, School of Applied Science and Humanities, Haldia Institute of Technology, Haldia. I completed my PhD in Chemistry from Cooch Behar Panchanan Barma University under the supervision of Prof. Gobinda Chandra De and Dr. Santanab Giri. My research expertise encompasses Conceptual Density Functional Theory (CDFT)–based global and local reactivity descriptors, Natural Bond Orbital (NBO) and ETS-NOCV analysis, Atoms in Molecules (AIM) analysis, superatom chemistry, global optimization methods, Time-Dependent Density Functional Theory (TD-DFT), external electric field–oriented chemical reactions, and aromaticity studies.
