About Me

I am Maurizio Ungaro, a nuclear physicist working in Hall-B at Jefferson Lab. This site collects my research, talks, simulation software, detector work, technical notes, and selected links. It is intended for collaborators, Geant4 and GEMC users, CLAS12 simulation users, and students looking for practical examples. My work connects nuclear physics analysis, detector operations, and simulation infrastructure, with a focus on making Geant4-based workflows easier to build, run, document, and share.

In my free time, I am learning to play hockey while enjoying watching my kid skate much faster than me.

What I Work On

Area Focus
Nuclear physics Nucleon structure, physics beyond the constituent quark model, and links between form factors and dressed quark mass, including the N → Δ(1232) transition and meson electro-production at high Q2.
Detector work Refurbishment, operation, maintenance, and calibration of the Low Threshold Cherenkov Counter detector in Hall-B.
Simulation software GEMC, CLAS12 Simulations, Web Submissions, and Open Science Grid production workflows.
Geant4 support Geant4 at JLab tutorials, examples, and support material for Jefferson Lab users.
