Research:

I am currently working on two research projects, one related to sea level studies and the other to tsunami research.

In the sea level group, we study corals to assess sea level fluctuations during the Holocene. These fluctuations are traditionally mapped by data derived from ice cores, speleothems and other proxies, giving us data which are accurate but not precise. In our research, we aim to improve this precision by narrowing down the margin of error.

In order to gain high precision we study fossil coral microatolls in tectonically stable parts of the Sunda Shelf, which record the sea level during their lifetime. By comparing the sea levels during their lifetime with today’s levels we can trace the sea level changes over time.

In the tsunami group, we focus on finding tsunami deposits on the coast of Northern Sumatra, in particular Aceh. Based on coral atoll studies, ancient earthquakes have occurred on Andaman-Aceh slip patch. Although the terrestial paleoseismic data is sparse, the region has experienced past tsunami events.

We are currently investigating the geologic record of the past tsunami events by studying ancient tsunami sediment deposits, best preserved in coastal lakes and caves. We can find additional information about the interaction between tsunami events and people by studying ancient and historical occupation sites through geoarchaelogical excavations.

Our improved understanding of the sequence of tsunami events in Aceh and improved precision of the South China Sea level curve will allow for better planning of coastline development.
