島根県を中心とした山陰地域に貢献する研究活動の改善の取組み

1. In addition, I deliver a special lecture to third-year bachelor students of our department (with more than 30 students in attendance) on ‘Indian Culture and the Education System in India’. This was aimed at promoting international understanding and cross-cultural exchange among local students.
2. October 1, 2024: I hosted students from Higashi High School (Matsue, San'in region) in our lab, explaining my research and showcasing ongoing experiments, contributing to local educational development in Shimane.
3. To promote interest in higher education and research, I participated in university outreach activities. August 8, 2024: During the University Open House, I presented my research and conducted live experiments for visiting high school students from across Japan, using PowerPoint and hands-on demonstrations to enhance understanding of university-level research.
