Satoshi’s research interests focus on semiconducting diamond growth and the device applications. He has succeeded the heteroepitaxy of diamond on cBN, n-type diamond growth, and deep ultraviolet LED formation by diamond pn junctions for the first time. His work has led to great research evolutions in new diamond applications, especially in the field of semiconductor devices. Satoshi has in excess of 25 years’ research experience on CVD and has published more than 150 peer reviewed journal papers with approximately 5000 citations. He is involved in the organisation of several international diamond conferences and workshops, including the International Conference on Diamond and Carbon Materials (Organising Committee, 2015~), Hasselt Diamond Workshop (Programme Committee, 1999~), and has also served as a Co-Chair of the Diamond Power Electronics Symposium in 2016 MRS Spring Meeting, and French-Japanese workshops on power electronics (2013~).
