Research Interests:

  • Quaternary record of paleoenvironmental changes
  • Sediments as high-resolution climate archives
  • Ocean-continent linkages
  • Relationships between climate, erosion, vegetation and precipitation (threshold & feedback processes)
  • Climate-environment-human nexus

During my career, I have focused on high-resolution (near annual) laminated records from continental margins as archives of environmental changes, either on the continent or in the ocean. I am particularly interested in the relationships between the terrestrial and marine realms, how they influence each other and how initial forcing are either exemplified or buffered by these complex interactions.

As I focus on the late Quaternary, the role of interactions in the climate-environment-human nexus are naturally one of my main research interests. In that respect, I value co-operation with other disciplines (such as with archeologists) to build more comprehensive pictures of human-climate interactions.

I study sedimentary processes along the source-to-sink pathway: sediment generation and transportation, response of ecosystems to climatic changes, sediment deposition and post-depositional alteration through diagenesis.
