岩石圈-大气层-电离层耦合
地震、海啸、火山喷发、热带气旋、龙卷风等地表或对流层的突发扰动事件能够激发大气声重力波。波动向上传播至高层大气，导致热层和电离层的扰动，已被大量观测证实。我们致力于刻画高层大气对地表突发扰动事件的响应特征和理解扰动事件期间岩石圈-大气层-电离层耦合的机理。

太阳风-磁层-电离层耦合
中小尺度（百公里及以下空间尺度）的电离层扰动，除了起源于低层大气和岩石圈，也可能由太阳风和磁层活动激发。我们关注能量从太阳风和磁层向电离层传递的物理过程，研究在精细时空尺度上，自上而下驱动的电离层扰动，旨在与低层大气和岩石圈驱动的电离层扰动进行区分，以追溯电离层扰动的来源。

全球电离层结构
公开发表的全球电离层地图拥有二十多年的总电子含量 (TEC) 全球格网数据，可以描述电离层在大尺度上的时空变化。我们采用图像处理技术提取TEC的经纬度空间结构，统计分析全球电离层的演化特征，并利用信息论方法量化太阳活动、太阳风和磁层条件、以及低层大气状态对全球电离层的影响。
