I am a Marie Sklodowska-Curie COFUND Fellow at the Institute of Physics, Czech Academy of Sciences (FZU) in Prague, working in the Department of Condensed Matter Theory. My research focuses on computational materials science with expertise in Density Functional Theory (DFT), Time-Dependent DFT (TDDFT), and ferroelectric materials for quantum electronics and neuromorphic computing applications.
I completed my Ph.D. in Electronics and Communication Engineering from PDPM IIITDM Jabalpur (2022), where I investigated the theoretical aspects of optoelectronic properties of III-V semiconductor alloys and quantum confined structures for infrared applications. My research combines first-principles calculations with advanced computational methods including VASP, ABINIT, GPAW, and multi-band k.p perturbation theory to explore novel materials for next-generation optoelectronic devices.
