About Me

I’m Mauri, a physicist working in Hall-B at Jefferson Lab. This site collects my research, talks, software projects, technical notes, and selected links.

Research

My research focuses on the internal structure and dynamics of the nucleon, in particular the physics beyond the constituent quark model and the link between form factors and dressed quark mass (see, for example, the N → Δ(1232) transition and the meson electro-production at high Q2 analyses).

Detector Work

I work on the refurbishment, operation, maintenance, and calibration of the Low Threshold Cherenkov Counter detector in Hall-B.

Simulation Software

I develop the GEMC Geant4 simulation framework and CLAS12 Simulations, including Web Submissions to the Open Science Grid (OSG). See, for example, our CLAS12 Project accounting.

Geant4 at JLab

Most recently I joined the Geant4 collaboration to support Geant4 at JLab.

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



Resource Description
GEMC Database-driven Geant4 simulations with a Python-friendly workflow.
Geant4 at JLab Geant4 tutorials, support material, and JLab-specific guidance.
Research & Talks Selected papers, presentations, and CLAS/CLAS12 technical notes.
Technical Notes Practical notes on software, systems, development, and workflows.
