0009-0009-9227-0422 About
I am Nitish Ghosh, and I completed my PhD in Physics from the Indian Institute of Technology Roorkee (IIT Roorkee), India, under the supervision of Prof. Lalita Sharma. My doctoral research focused on relativistic atomic-structure calculations, electron-impact excitation processes, low-energy scattering, continuum-state calculations, and collisional-radiative modelling for plasma spectroscopy and diagnostics.
My research involves the calculation of atomic parameters such as energy levels, transition probabilities, oscillator strengths, lifetimes, hyperfine-structure constants, and electron-impact excitation cross sections. I have used methods and codes including MCDHF, MBPT, GRASP2018, FAC, ColRadPy, and relativistic distorted-wave theory. I have also worked on fine-structure-resolved collisional-radiative models to interpret emission spectra from laser-produced and discharge plasmas.
My broader research interests include atomic data for plasma modelling, non-LTE plasma kinetics, plasma diagnostics, fusion-relevant impurities, highly charged ions, low-energy electron–ion scattering, and astrophysical opacity applications. I am particularly interested in connecting accurate theoretical atomic data and continuum processes with spectroscopic modelling for laboratory, fusion, and astrophysical plasmas.
