My research is primarily concentrated on the real-time monitoring of Laser Powder Bed Fusion (L-PBF) additive manufacturing process, utilizing an extensive variety of sensing approaches to detect defects and expedite the qualification of manufactured parts. I am also interested in the development of physics-informed, data-driven PSPP models that leverage the synergistic fusion of physical principles and machine learning for advancements in predictive capabilities and the overall efficiency of manufacturing processes.
