Associate professor Chiba has conducted a variety of theoretical research on thermoelasticity of composite materials since university. He specialises in applying probabilistic methods to engineering problems and developing a novel method for the reliability design of advanced composite materials. Moreover, Chiba has considerable experience doing research in the area of heat and mass transfer; he conducted experimental/numerical research on heat transfer with phase change as a joint research project with an air-conditioning company. All the work mentioned above were carried out in collaboration with researchers from other Japanese universities: Iwate university, Ishinomaki Senshu university, Yamagata university, etc. Since 2008, Chiba has been pursuing research on plastic working, and specifically focuses on the development of high value-added materials through plastic working, such as rolling, extrusion and drawing. In early 2016, he undertook an atomistic study on grain boundary stability in metal, which is a collaboration with Thai researchers.
