Andreas Ekström
Andreas is a theoretical nuclear physicist. He focuses his research on theoretical models of the strong force that binds protons and neutrons in atomic nuclei. The overarching aim is to create quantum mechanical models to describe and predict the fundamental properties of atomic nuclei.
