Brief Description of the Lab
Our lab focuses on investigating the source, distribution, and diagenesis of biogenic organic compounds in marine environments. Most biogenic compounds are produced in the surface ocean through photosynthesis, and they are subsequently subject to different biogeochemical processes. For example, some are degraded or modified by bacteria or zooplankton; some are preserved in a long time scale by interaction with minerals. Elucidating these processes can not only help us to better understand global carbon cycle, but also provide valuable information for paleoceanography and paleoclimate studies. We are also interested in geochemical behaviors of petroleum hydrocarbons in marine environments.
