（一）高性能计算地震学:

基于谱元法（Spectral-element method）的地震波数值模拟，主要研究有起伏地形的非弹性介质中的波传播现象。借助超算平台（比如神威太湖之光）对全球三维内部结构、青藏高原区域壳幔结构、以及城市浅部探测等问题进行全波形反演成像。利用卷积神经网络等人工智能手段，来研究地震信号的智能拾取，提高波形反演中的数据处理效率。

（二）海洋地球物理：

主要研究海底地震仪的数据处理技术，发明了瑞利波导纳法 (Rayleigh-wave Admittance) 来研究深海沉积层的速度或者监测岩浆囊的动态变化。利用海底地震仪台网记录的远震面波反演速度和Q值模型，研究洋中脊和俯冲带小尺度运动的动力学机制。

（三）理论地震学：

研发针对面波的有限频率理论，研究滞弹性结构（衰减Q值）对面波的影响。应用地震面波反演大陆岩石圈的速度和Q值，研究岩石圈的流变机制。
