Research Interest

My research has focused on the paleoaltitudes and paleoecology of the Tibetan Plateau and global/monsoonal-arid land climate change, using bio-organic-geochemical proxies based on the hydrogen isotopes of leaf wax n-alkanes (δ2Halk), paleothermometers (glyceryl dialkyl glycerol tetraethers (GDGTs) from microbial cell membranes) and paleoecology (e.g. terpenoids).

Research Field: Uplift of Tibetan Plateau and environmental change
