The annual Misasa International Student Intern Program for advanced undergraduate (3rd to 4th year) and M.Sc. students was planned as part of the COE-21 program with the purpose of promoting international collaborative research and education. It has been conducted as a well-developed educational program of ISEI. Students work closely with ISEI faculty members and their research groups on currently active research projects over a month. They are exposed to the state-of-the-art research facilities and activities at ISEI, and gain first-hand scientific research experience through this program.
