Current Research

My main research motivation is to understand co-evolution of climate/geochemical cycles/ecosystems. Effect of climate change spreads to top predators in ecosystems via changes in geochemical cycles, and three systems have evolved along with interaction between each other. By combination use of high-end geochemical techniqies, together with paleontological and ecological methods, our research team studies interaction and evolution of the three systems at various spatial and temporal scales.
