Courses:  An Introduction to Geochemistry ，

　　　 　Advance of Geochemistry ，

　　　　 An Introduction to the Earth System；

Research field：

(1) Isotopic geochronology, cooling history and exhumation mechanism of ultrahigh pressure metamorphic (UHPM) rocks;

(2) Isotope and trace element geochemistry of ultrahigh pressure metamorphic rocks and igneous rocks in orogenic belt to trace the continental collision and mountain root removal processes.

(3) Trace element behaviour during progressive metamorphism and retrograde metamorphism of UHPM rocks.

(4) Adakitic rocks and basaltic rocks geochemistry to understand partial melting and delamination of thickened continental crust and and crust-mantle interaction.
