主要從事物理海洋和海洋遙感方面的研究，近期主要成果包括：用衛星高度計和散射計數據檢驗了經典地轉渦流理論，發現並解釋了全球海洋中不符合經典理論預測的區域；發現了去除衛星高度計儀器噪音影響的方法，從而解決了衛星高度計觀測中長期存在的“速度功率譜藍移”的問題；發現海洋中非潮汐高頻信號的混疊效應對高度計觀測中尺度過程的影響，並提出了解決方法；提供了海盆尺度水體本徵震蕩的觀測證據；在研究中尺度海洋垂直耦合過程中引入典型相關分析方法，並因此發現了海洋上層和深層中尺度渦的相互作用現象；發展了一套降低氣候模式系統誤差引起的偏差的方法，改善了預測未來極端天氣事件變化的能力；揭示了海洋表面和海底能量影響海洋內部混合的穿透深度；用Argo浮標結合衛星觀測揭示了北太平洋經向熱輸運；發現海流中的Coriolis-Stokes效應，改善了用衛星觀測反演流的精度。以上成果發表在JPO、JGR、GRL、OceanModeling、DSR、Climatic Change，Jtech等國際知名期刊。
