I am insterested in topics of plasma physics and controlled fusion: plasma-surface interactions, divertor-relevant physics, atmospheric plasma sources and its applications.

筑波大学プラズマ研究センターの「プラズマ-材料相互作用」グループを担当しています。
核融合炉における周辺プラズマと炉壁の相互作用に着目し、直線型プラズマ装置を用いた高温プラズマー金属壁の相互作用の研究を行っています。また、プラズマー材料相互作用の産業応用を目指して、大気圧プラズマ源の開発及びプラズマ計測を行っています。プラズマ照射による材料の表面・内部変化に興味がある方、歓迎します!

Mar 24, 2026	2026/3/24-27の日程で、九州大学の古閑研究室に訪問しました。古閑研開発の大気圧DBDプラズマ装置のワークショップに参加しました。奥村先生のご指導でプラズマ源の組立や動作試験を行い、筑波大学に同機の運用環境を整えていきます。 I visited the Koga Laboratory at Kyushu University. I participated in a workshop on the atmospheric-pressure DBD plasma device developed by the Koga Lab. Under Professor Okumura’s guidance, I assembled the plasma source and conducted operational tests, and we are now preparing the operational environment for this device at the University of Tsukuba.
