I am a researcher in computational materials science with a PhD in Physics, specializing in DFT studies of lead-free halide double perovskites. My research focuses on structural, electronic, optical, mechanical, thermodynamic, and photocatalytic properties for energy applications. I use CASTEP, WIEN2k, and SCAPS-1D, with particular interest in cation engineering, photovoltaics, optoelectronics, and theory–experiment collaboration.
