Since I joined Sophia University in April 2000, I have been engaged in education and research on applied power conversioncontrol for many years. Our research field is approaching the interdisciplinary area among electrical, mechanical, civil, and information and communication engineering through application to transportation systems such as railways. It is ideal for teaching young students who can contribute to voluntary technological development in response to the needs of a diverse society becoming increasingly complex, advanced, and internationalized. I am looking forward to your contribution and guidance. Students and researchers for studying and researching are welcome to my laboratory.
