Guanhong Chen is a first-year Ph.D. student in Mechanical Engineering at the School of Engineering, College of Science and Engineering, University of Galway, Ireland. He is also affiliated with I-Form, the SFI Research Centre for Advanced Manufacturing at University College Dublin, where he conducts research on metal additive manufacturing. His doctoral research focuses on multiscale and multiphysics modeling of microstructure evolution in laser-based powder bed fusion (PBF-LB). By integrating phase-field modeling, crystal plasticity, and computational fluid dynamics, his work aims to establish predictive relationships between process parameters, thermal history, and crystallographic texture evolution. The research provides a computational framework for understanding and controlling microstructural development in metal additive manufacturing. Before beginning his Ph.D. studies, Guanhong worked on computational materials design during his master’s program, resulting in publications in Journal of Materials Processing Technology and Materials & Design. He is also the inventor of two Chinese national patents and one international patent in the field of materials processing and design. Guanhong has participated in several international academic conferences and competitions. He received the Best Student Paper Award at the 2024 International Symposium on Structural Integrity (ISSI 2024) for his research on microstructure modeling in metal additive manufacturing. His research interests include process–structure–property relationships in metallic systems, high-performance numerical simulation, and integrated modeling–experiment approaches for additive manufacturing.
