What I Work On

• Nuclear physics: nucleon structure, resonance-region analyses, and the transition between hadronic and partonic descriptions through single-meson electroproduction, including the N → Δ (1232) transition and meson electroproduction at high Q².
• Detector systems: operation, maintenance, calibration, and performance studies of the CLAS12 Low Threshold Cherenkov Counter, including pion/kaon discrimination in Hall-B.
• Simulation software: development of GEMC and GEMC3, a database-driven Geant4 framework with a Python-friendly workflow for detector and radiation-transport studies; tagged CLAS12 geometry and simulation releases, digitization workflows, and geometry tools.
• Distributed computing: CLAS12 production on the Open Science Grid, with web and batch submission tools and HTCondor workflows for running simulations on distributed resources, and early work exploring HPC allocations such as NERSC to complement OSG production.
• Scientific computing and support: Geant4 at JLab, reproducible simulation workflows, tutorials, examples, and user-facing documentation.

Biography

Maurizio Ungaro is a Staff Scientist in Hall-B at Jefferson Lab. His work connects nuclear physics analysis, detector systems, and simulation infrastructure. He develops and supports Geant4-based simulation workflows, GEMC and GEMC3, Python tools through pygemc, and CLAS12 simulation releases. His recent work includes CAD mesh repair and optimization, reproducible geometry and tracking benchmarks, interactive visualization with Geant4 XR integration, multilingual tools, and portable build environments. He also maintains simGrid production workflows on the Open Science Grid and writes technical documentation for users.

His detector work includes the CLAS12 Low Threshold Cherenkov Counter, with responsibilities in operation, maintenance, calibration, and detector performance. His research focuses on nucleon structure, meson electroproduction, resonance-region analyses, and the transition between hadronic and partonic degrees of freedom.

Earlier and collaborative work includes experiments in Japan through the LEPS/SPring-8 collaboration and participation in Heavy Photon Search, a dark-sector search collaboration at Jefferson Lab.
