Associate Professor / HONMA Tsuyoshi
Dr. Homma entered our university from a technical college and worked for a company. After that, he returned to our university and taught us in his laboratory. He is an amiable professor and actively participates in laboratory events.

Research Content

Glass has been an essential material for human society since B.C. In modern days, glass is used not only for glass containers and sheet glass but also for displays and optical fibers that support the latest digital society. In our laboratory, we are engaged in research based on the creation and process development of new functional glasses and glass-ceramics that contribute to constructing a future society. Recently, we have succeeded in developing an all-solid-state sodium-ion battery composed of oxide ceramics without using rare metals in an industry-academia collaboration.

A Day in the Lab

Prof. Homma respects the independence of his students. Therefore, in this laboratory, students proceed with their studies at their own pace. If students manage themselves well, they can have a meaningful study life. Seminars include:
A progress report (once every two weeks).
A paper introduction seminar (once a week).
A machine learning seminar (once a week).
Progress reports on the study are given one-on-one with the professor, allowing for in-depth discussion. Our lab holds various events, and students get along very well.
