I am part of the 4D-REEF research consortium studying the past, present and future of turbid coral reef ecosystems. My research focuses on temporal dynamics in large benthic foraminifera (LBF) assemblages from the Spermonde Archipelago (Indonesia). I will dive into long and short term shifts as well as rapid seasonal changes in LBF communities, using an integrative approach combining sediment samples, cores, remote sensing, DNA metabarcoding and traditional microscopy methods.

Ever since I can remember my love for the ocean has been growing. Thanks to the 4D-REEF program, I have the opportunity to better understand LBF shifts in turbid reefs through time.
During my studies, I had the opportunity to conduct fieldwork in the Maldives and Indonesia; two journeys that opened my eyes to coral reef ecosystems. After studying the incorporation of foreign particles by marine sponges, I am keen to dive into the beautiful world of large benthic foraminifera. My research will contribute to our understanding of factors driving community changes over three different time scales. Results from my study will resolve a part of the puzzle that 4D-REEF aims to complete regarding turbid reef evolution in the Coral Triangle.
My research focuses on:
- Quantifying temporal shifts in LBF assemblage composition
- Linking molecular and morphological methods for LBF community analysis
- Assessing the impact of river discharges on LBF assemblages
- LBF as a bioindicator to foresee reef degradation
