Developed a complete Process–Structure–Property (PSP) surrogate framework for polycrystalline fracture mechanics, combining OpenPhase phase-field simulation with Gaussian Process Regression. • Ran 36 OpenPhase 1.0.1 phase-field simulations (6×6 full-factorial DOE) varying GB energy ratio σ/G (0.1–2.5) and applied strain ratio ε/εc (0.8–1.8) • Extracted 14 microstructure-fracture features from 1.7 GB of VTS output via custom Python pipeline • Trained GPR (Matérn ν=2.5), GBR, and RF surrogates with 5-fold CV

World's largest single-location oil refinery complex. Led static equipment integrity and turnaround engineering for refinery and petrochemical units. • Performed root-cause metallurgical and corrosion failure analysis for pressure vessels, piping, and heat exchangers aligned with API 571 degradation mechanisms • Developed Corrosion Control Documents (CCDs) and Integrity Operating Windows (IOWs) per API 580/581 Risk-Based Inspection framework • Applied NDT methods (DPT, RT, UFD) and ASME/API codes for fitne
