Research Interests

Professor Sparveris is currently pursuing his research at the Thomas Jefferson National Accelerator Facility, VA, USA and at the MAMI Microtron, Mainz, Germany, where he is conducting experiments by scattering unpolarized and polarized electron beams from unpolarized and polarized nuclear targets. The goal of his research is to address some of the fundamental questions in nuclear physics, such us understanding the quark-gluon substracture of the nucleons, to decode the interplay of the mesonic and the quark-gluon degrees of freedom inside the nucleon, to understand the distributions, polarizabilities and the shape of the nucleon as well as the dynamics that lie underneath these properties, and to explore deeper the dynamics of the few-body nuclear systems.
