研究领域
My research focuses on the paleo-climate and paleo-ecological changes in Antarctica due to its high latitude position, uncomplicated ecosystems and sensitivity to fluctuations in global climate. I am particularly interested in the historical changes of hydrological cycle and central type of metabolism in heterotrophs, and then study mechanisms controlling climate change and environmental response to climate change over the past 3,000 years.
I have a boad interests in the use of lipid biomarker and their carbon and hydrogen isotopes preserved in lake and ocean sediments in Antarctica. My understanding of organic analytical chemistry and isotope organic geochemistry have enabled me to accurately indentify the sources of lipid biomarkers in Antarctica, and decode what climate information captured in the compound-specific carbon and hydrogen isotopes. I understand such isotope signals generated in exant organisms through laboratory pure cultures and modern natural samples, and employ them to lake and ocean sediment cores. I seek to provide new reliable proxies for understanding historical climate and ecological changes in Antarctica.
