Hi, I’m Alon 👋

Physics PhD student focused on scientific software, simulation, algorithm development, and collaborative workflows. Experienced with large production codebases, cross-institution workflows, and research-grade debugging. Comfortable working at the intersection of physics and software engineering.

Selected Projects

GEMC / CLAS12 Target Implementation (RG-M)

Production geometry implementation merged into an international, multi-institutional simulation framework

  • Implemented Ar, C, and Sn target geometries and configurations
  • Code merged into the official repositories
  • Author of a published CLAS12 technical note documenting the implementation (CLAS12 Note 2026-001)
  • Tech stack: Perl, CAD-based geometry workflows, GEANT4 / GEMC simulation framework

PR (clas12Tags): gemc/clas12Tags#64
PR (clas12-config): JeffersonLab/clas12-config#119
Technical note: https://misportal.jlab.org/mis/physics/clas12/viewFile.cfm/2026-001.pdf?documentId=185

SuSA Electron-Mode Validation (GENIE)

Bug identification and fix in a production neutrino–nucleus interaction generator

  • Identified a bug where the GENIE event generator (v3.2) generated only 1n1p final states for 2p2h SuSA-MEC
  • Traced the issue to missing/misused hadronic tensor tables and incorrect pair selection logic
  • Integrated new tensor tables, fixed probability calculations, and restored 2p / 2n final states
  • Corrections merged into the official GENIE codebase (v3.4+); contributor within the GENIE collaboration

PR: GENIE-MC/Generator#242
Detailed validation in MSc thesis, Section 9.1.3
