While finishing my PhD project on coral reef ecosystems, I am diving into two new topics: 1) the molecular intricacy of foraminifera and how it evolves through space, time and symbiosis, and 2) establishing a baseline of the micro-benthic community in the North Sea prior to the construction of a Dutch 'nature-friendly' offshore wind park. I am very excited to discover what hides below the waves, on the seafloor of the North Sea.

Research
focus

From coral reef foraminifera from Indonesia to the North Sea, I am driven towards better understanding the intricacy of the foram genome and how it varies across species, symbiosis and ecosystems. 

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 developing methods to assess reef foraminifera community composition using metabarcoding, I am keen to dive into a new ecosystem: the North Sea.

Ecology of large benthic foraminifera

Benthic foraminifera are widely seen as good environmental indicator. When conditions change, so will the LBF species occurring on a site. Because of their short generation times, LBF assemblages, with a generation time of 0.5-2 years) will change faster…

Impact of urbanisation on coral reef ecosystems

Here we assess the historical impact of human settlement on coral reef environments adjacent to two major conurbations in southeast Asia, namely Jakarta and Makassar. This will be the first study to assess on a large spatial scale how the historical…
