RESEARCH INTEREST AND ACADEMIC CONTRIBUTION TO COMMUNITY
My research is focused on how Earth System responded during climate change events in geological time, with a particular interest in the co-evolution of ocean and atmosphere chemistry. To this end, my main tools are the application of stable isotopes and sedimentary geochemistry, in combination with atmosphere–ocean models. The detailed projects are outlined as below:
(1) Shed light on a long-term redox evolution history across the Panthalassic transect from the late Pliensbachian to early Toarcian, with an upwelling model accounting for the enrichment of iron on the shelf.
(2) Unraveled a long-term sulfur cycle in the Panthalassa from the late Pliensbachian to early Toarcian, emphasizing the role of local sedimentary environment in affecting pyrite S-isotopes and pyrite sulfur concentrations.
(3) First identification of the T-OAE in the Hebrides basin based on the preserved T-CIE record in the Raasay section, revealing spatial variability in redox conditions and enhanced hydrological cycling and chemical weathering at a high-latitude sub-tropical site during the T-OAE.
(4) Uncovered the upper-ocean redox conditions in NW Tethys during the T-OAE using I/Ca and pointed out a potential cause-and-effect link between biotic turnover and local upper-water redox.
