Large parts of the earth surface are shaped by sedimentary processes. I am fascinated with complex sedimentary features, their morphology, and understanding the mechanisms that built and modified these features. Based on my background in geophysics I am using geophysical techniques to image the morphology, extent, and internal structure of complex sedimentary features to understand their evolution as well as the controlling processes. I am exploring new ways to combine and interpret different data sets using Geographic Information Systems (GIS) and to integrate geophysical data with information from sediment cores or biological observations. I am particularly interested in estuarine processes, sediment transport and deposition on continental margins, and glacially-influenced sediments. It is my goal to better understand the evolution of present and past morphology, what causes and controls deposition, erosion, and, hence the shape of sedimentary features, and how these features are linked to past glaciations and habitats.

Some of my projects include:

  • Hudson River Research ( details )
  • Amundsen Sea, West Antarctica ( details )
  • Sedimentation processes along the Westantarctic continental margin ( details )
  • Hudson River data visualization ( details )
