首開并主講《航空發動機噪聲控制與測試》研究生專業理論課、參講《複變函數》本科專業課等。

航空發動機氣動聲學和短艙聲襯降噪技術，包括高效聲襯設計方法、寬頻高效聲阻抗提取技術、寬頻線性低流阻航空聲襯與聲阻抗建模、聲學超材料等。

提出并建立一套高精度、高流速、高頻、高效的聲襯聲阻抗提取實驗方法+平台，覆蓋航發風扇0.2-10kHz主要頻率範圍，打破NASA方法3kHz上限，效率提高2-3個量級，且測點數量大幅減少。提出一種針對航空發動機圓/環管、有限長、局域/非局域兩大類聲襯的高效解析設計方法，揭示了有限長耗散型聲襯的降噪機理。發展航空發動機先進多自由度金屬絲網寬頻、線性、低流阻聲襯新構型，研究其高聲強效應、掠流效應、寬頻特性等并建立聲阻抗模型。
