Research interests

1.Basalt Geochemistry: evaluating the effect from shallow magma chamber or deep mantle processes.

2.Crustal melting: understanding the critical melt porosity during crustal melting and applying it for understanding geophysical and geochemical observations.

3.Non-traditional stable isotopes: developing new methods and applying them in petrology study.
