Dr. Lin Gao is an Assistant Professor in the Department of Mechanical Engineering. His research focuses on fusion-based metal additive manufacturing (AM), particularly on elucidating the intricate relationships among processing, microstructure, and material performance. He leverages state-of-the-art synchrotron X-ray characterization techniques to study additive manufacturing processes operando, aiming to uncover the underlying mechanisms behind highly dynamic phenomena. During his postdoctoral appointment in the Nuclear Science and Engineering Division at Argonne National Laboratory, Dr. Gao investigated additively manufactured materials for structural applications in nuclear reactors. With a strong background in both fundamental understanding and practical applications, Dr. Gao is dedicated to advancing integrated material-process-product co-design for metal AM.
