Protons and neutrons, the building blocks of visible matter, are complex systems of valence quarks and dynamically produced quark-antiquark pairs, bound together by gluons. A major goal of modern nuclear physics is to understand how the structure of nucleons and the interactions between them arise from the dynamics of quarks and gluons described by the theory of strong interaction, Quantum Chromodynamics. My academic interest focuses on exploring the nature of the strong interaction and the way it manifests itself in the properties and interactions of hadrons. Pursuing this scientific direction, I have been studying experimentally the features of nucleons - the basic constituents of visible matter - from the source of their mass to the spin properties.

In my research, I study the proton spin structure in electron-proton/nucleus interactions at the CLAS12 Experiment at Jefferson Lab. I focus on Semi-Inclusive Deep Inelastic Scattering processes, which provide insights into the 3D partonic structure of nucleons and nuclei in momentum space. Additionally, I am a member of the STAR collaboration at Brookhaven National Laboratory, where I investigate proton spin structure with jets.

Another significant aspect of my work involves the development of calorimetry for future investigations of proton structure at the Electron-Ion Collider (EIC). I have been leading the development of the Barrel Imaging Calorimeter for the ePIC detector since 2021, currently serving as the deputy Detector Subsystem Coordinator. This endeavor has been made possible through the support of Argonne LDRD and EIC R&D grants, which have enabled me to actively participate and drive forward this project. My research interests within EIC Physics primarily focus on nucleon structure investigations in Semi-Inclusive Deep Inelastic Scattering (SIDIS) with hadrons and jets. However, I am equally excited about exploring other opportunities that the Electron-Ion Collider offers beyond SIDIS, ensuring an immensely diverse and dynamic field for exploration.

How did I end up where I am now?

During my PhD, I delved into probing the proton-neutron mass difference, which arises from strong interactions, by examining the up and down quark mass difference through the measurement of charge symmetry breaking observables at the WASA Experiment. Additionally, I contributed to measurements of diffractive processes, such as central exclusive meson production, aimed at testing Quantum Chromodynamics (QCD) in the confinement regime at the CDF experiment.

My first postdoctoral appointment was dedicated to developing polarimetry techniques for the search for an electric dipole moment (EDM) of the proton and deuteron at the JEDI collaboration. Subsequently, my interest in spin physics led me to join the STAR collaboration, where I have been studying the spin structure of the proton with a focus on jets.
