研究兴趣：

全球玄武岩开展有关源区和过程的岩石学和地球化学。通过玄武岩的元素、放射成因同位素（如Sr、Nd、Pb、Hf）和稳定同位素（如Mg、Fe、Zn）组成，示踪地球深部地幔（下地幔和地幔过渡带）的物质组成，了解地球内部和地球表层之间的物质循环过程。

主要成果：

（1）运用Mg、Fe、Zn等稳定同位素研究全球代表性洋岛玄武岩，揭示了EM1、EM2和HIMU等深部地幔端元的属性，从而率先建立了深部碳循环过程与地幔端元形成之间的内在联系。

（2）通过分析碱性玄武岩关键元素对的分馏机理，识别出含碳酸盐沉积物在地幔过渡带发生的深部熔融事件，从而建立了深部碳循环与大陆碱性玄武岩的成因联系。

科研项目：

国家自然科学基金重点项目1项，“从大陆火山岩视角了解深部地幔化学储库的属性（2022-2026）”

面上项目4项和青年项目1项，“南太平洋Louisville海山玄武岩的成因与源区特征”和“东北新生代高镁安山岩的成因”等
