During September 2025, Andrew Schick modernized the epem_ml_skim plugin in the JeffersonLab/halld_recon repository, focusing on JANA2 compatibility and extensibility for multi-nucleus analyses. He refactored the plugin’s structure and histogramming logic using C++ and the JANA Framework, enabling support for nuclei beyond Pb208 through enhancements to the DCPPEpEm_factory. This work streamlined the setup process for diverse experimental conditions and improved maintainability, laying groundwork for future physics runs with flexible analysis targets. Andrew’s approach demonstrated depth in software engineering and data analysis, addressing both immediate experimental needs and the long-term migration to modern plugin architectures.
