In June 2025, Payam Kasaie enhanced the SHIELD calibration workflow in the tfojo1/jheem_analyses repository, focusing on demographic and syphilis diagnosis modules. He consolidated calibration processes, improved visualization and registration, and strengthened MCMC diagnostics to ensure robust convergence assessment. Using R programming, statistical modeling, and simulation, Payam tuned calibration parameters and updated PK configurations, resulting in a stable and reproducible pipeline. His work emphasized clear documentation and commit-driven traceability, enabling more accurate and timely clinical decision support. The depth of these enhancements addressed both workflow efficiency and analytical rigor, laying a foundation for reliable future calibration and analysis.
