  • Degradation of 'unconventional' carbon substrates

I am intrigued by the transformation of important but ‘unconventional’ carbon substrates such as methane, oil and plastics and their fate in aquatic (microbial) food web structures. With the aid of a multidisciplinary approach, my research particularly focuses on the geomicrobiology (including organic biogeochemistry) and spatiotemporal aspects of aquatic carbon cycling and the turnover of unconventional carbon substrates in sediments and the water column. In addition, I am also interested in lipid biomarkers as chemotaxonomic markers, and proxy indicators recording (paleo) environmental conditions.

Hidden secrets in the North Sea: An expedition addressing sea-level rise, oxygen loss and microbial breakdown of methane
The North Sea still hides many secrets. A joint team of researchers from the Royal NIOZ Sea Research, TNO, Deltares, Utrecht University and VU University Amsterdam set out on an expedition with the research vessel Pelagia to answer some questions…
