Associate Professor / OTSUKA Yuichi
Associate Professor Otsuka is a highly dedicated researcher who brings together engineering and knowledge from chemistry, biology, and medicine. He is deeply committed to supporting students and provides careful guidance in both research and education. He stays close to students’ needs and helps them move forward step by step.

Research Content

This laboratory focuses on structural and mechanical analysis of biomaterials and their durability evaluation. Research includes fretting wear assessment at biomaterial interfaces and optimization of acetabular cup geometry to suppress loosening in hip implants. In addition, structural optimization of porous biomaterials and safety evaluation through durability testing are conducted. Recently, experimental jigs fabricated using metal and polymer 3D printing have been developed. The laboratory provides a research environment that integrates analysis and experiments, allowing flexible projects tailored to diverse interests and expertise.

A Day in the Lab

This laboratory holds an English morning seminar jointly with Professor Miyashita’s Laboratory of Materials and Joint Strength. In these seminars, students present their research progress and engage in active discussions, naturally improving their English communication skills. International exchange events are also organized, welcoming students and faculty from overseas universities to broaden global perspectives. Master’s and doctoral students are provided with individual desks and laptop computers. Well-equipped experimental facilities and measurement instruments are available, and new equipment can be introduced when necessary, providing a supportive environment for focused research.
