Research Interests

  • Organic biomarkers (eg. plant pigment, lignin-phenols, fatty acids) in the marine environment
  • Biogeochemistry of the carbon cycling in the coastal/estuarine systems
  • Environmental chemistry

I have focused on the organic carbon cycling in large river dominated delta front estuaries (LDEs). Multiple biogeochemical proxies have been applied in my Ph.D project. For example, radionuclides, organic biomarkers, stable carbon, and radiocarbon isotopes were analyzed to explore the sources, age, and digenetic status of organic carbon in the East China Sea shelf sediments off the Changjiang River, one of the biggest river systems in the world. Low oxygen tolerated foraminifera assemblages were also applied in my study to link the carbon cycling with eutrophication and the mechanisms of hypoxia. In addition, I have studied the dissolved and particulate organic carbon cycling in the sediment and/or water column in a variety of projects such as the Mechanisms Controlling Hypoxia off the Mississippi River delta in Gulf of Mexico (GOM) and the Deep Water Horizon oil spill in GOM. Therefore, the comparison of organic carbon cycling in the two LDEs between the GOM and the East China Sea was initially researched.
