Introduction
I have a PhD in theoretical nuclear physics, my research interests are focused on deepening our understanding of nuclear reaction theories. I am interested in scattering, Coulomb excitation, and breakup of exotic nuclei. In addition, I am working on the energy and mass dependencies of the microscopic optical and dynamical potentials.
