BIOGRAPHY:

I am presently engaged in the field of theoretical nuclear physics, focusing on fusion dynamics, alpha, proton, and cluster radioactivity, as well as nuclear decay processes. My research emphasizes the role of nuclear structure effects including deformation, shell closures, pairing effect, isospin effect, and halo/loosely bound propertieson reaction and decay mechanisms. I work extensively with various theoretical models such as coupled-channels calculations using phenomenological and microscopic nuclear potentials, the relativistic mean-field (RMF) theory, the Skyrme energy density formalism, the Dynamical Cluster-Decay Model (DCM), the Preformed Cluster-Decay Model (PCM), and the Coherent Density Fluctuation Model (CDFM). My group explores topics like sub-barrier fusion with exotic nuclei, nuclear incompressibility, and the synthesis of superheavy elements. We are also integrating machine-learning-assisted approaches to refine predictions in nuclear stability and reaction dynamics. These efforts contribute toward developing advanced nuclear models for systems near the drip lines, supporting experimental programs and opening up applications in nuclear energy and medical isotope production.

During my postdoctoral research, I developed a schematic model to investigate the role of break-up processes in sub-barrier fusion involving weakly bound halo nuclei. The study revealed that proton halo systems lead to a stronger fusion enhancement due to a more pronounced reduction in the Coulomb barrier. It also highlighted the importance of distinguishing between complete and incomplete fusion, showing their sensitivity to target properties. My PhD work laid the foundation for these investigations, focusing on heavy-ion reactions across various mass regions using the DCM and the ℓ-summed extended Wong model. These studies incorporated deformation and orientation effects, with nuclear proximity potentials derived from the semi-classical extended Thomas-Fermi model based on Skyrme energy density formalism. A major objective was to understand fusion hindrance through the barrier modification influenced by angular momentum, nuclear shapes, and density-dependent parameters. Together, my academic journey has been dedicated to advancing the theoretical understanding of nuclear reaction dynamics and structural effects, with relevance to both fundamental science and practical applications.
