Outline Activities
My speciality in research is on the academic basis of strengthening mechanism and its application technologh aiming the development of mechanical proprerties in steels. Our group including the other staffs and students has received many awards such as paper award, academic award and poster award in international conferences through the research activities. In the field of education, I contribute to many social education programs organized by academic societies and institutes as well as to the education of students in Kyushu university. In 2005, I built up the RESEARCH CENTER FOR STEEL in our university and, since then, I have been operating the collaboration reserches between steel companies and universities and collaborated education programs for graduate students as the head of RESEARCH CENTER. In our university, I have engaged in the task of vice-dean and councilor in the Faculty OF ENGINEERING. On the social activities, I have responsibilities with the management of IRON AND STEEL INSTITUTE OF JAPAN and JAPAN SOCIETY FOR HEAT TREATMENT as one of directors, and also contributed to the scientific development as one of the judging committee members in JSP, NEDO and so on. In this decade, I have organized three distinguished international conferences as the chair person and I have been contributing to the global development of science person as an international committee member in many international conferences such a THERMEC.
