極限状態の一つとして臨界温度と臨界圧力を超えた状態である超臨界流体の科学と工学への応用を研究しています。分離プロセスとして超臨界二酸化炭素や亜臨界水を使って天然物から生理活性成分を抽出・精製する研究などをしています。反応プロセスとして亜・超臨界水によるバイオマスの資源化や燃料化の研究などをしています。一方、異分野融合研究として化学と電気技術の融合プロセスを開発しています。亜・超臨界流体中でのパルスパワーによる放電プラズマやレーザーアブレーション、電気分解反応による化学反応や材料調製の新規なプロセスを研究しています。国内外の大学や企業との共同研究を積極的に推進し、基礎から実用化に至る研究を行っています。
