Kuga研究室では、建物内での人間の呼吸と感染症の伝播、室内環境の質に関する問題を、コンピュータシミュレーション技術を中心に研究しています。具体的には、咳やくしゃみによって放出される飛沫がどのように室内を移動し、他の人に吸入されるかを数値計算で再現します。実際の人間の鼻腔・気管・肺の形状をモデル化し、空気の流れと粒子の輸送を同時に計算することで、感染リスクを定量的に評価しようとしています。また、ウイルスが呼吸器に沈着した後の動態についても研究を進めています。呼吸器内の粘液層でウイルスがどのように増殖し、感染がどのように進行するかを、ウイルス動態モデルと流体シミュレーションを組み合わせて解析しています。さらに研究室では、室内の換気効率や二酸化炭素濃度といった室内環境要因が、人の睡眠や作業効率に与える影響についても実験と計算の両面から調査しています。これらの研究を通じて、Kuga研究室は感染症対策、室内環境設計、公衆衛生に貢献できるデータやシミュレーション手法の開発を目指しています。
