Our research interest is exploring the process-structure-property relationships in structural metals, with particular emphasis on grain boundary microstructure, microchemistry, and their roles in fracture, cracking and corrosion properties in the environments. While the lab is mainly interested in the fundamental material science, we keep close ties to industry.

Current research in the Lab is categorized into the following areas: 1) metal additive manufacturing and additive alloy development; 2) structural alloys and composites for extreme environments; 3) high-throughput alloy discovery; 4) environmental fracture and cracking of structural metals; 5) corrosion and oxidation.

Our interest primarily focuses on exploring the structure-processing-property relationships of advanced alloys and composites in extreme service environments. The research involves three thrust areas: (1) innovative manufacturing technologies to support energy, aerospace, and oil & gas industry; (2) structure alloys and composites for extreme environments; (3) high-throughput alloy development by utilizing advanced manufacturing, characterization, and data analytics; (4) environmentally assisted cracking.
