Research Interest

I am an organic geochemist with a particular interest in the power microbial biogeochemistry.  Microscopic organisms have been shaping their environment since the beginning of life on Earth. Lipids are incredibly resistant molecules, and are preserved over long periods of time in the geologic record, acting as chemical fossils to these microbes. Using lipids to extract information about the environmental conditions in which these organisms once lived, I aim to develop biomarkers for specific microbial processes within biogeochemical cycles. Currently, my research projects focus on aerobic methanotrophy and anearobic ammonium oxidation. I also use a combination of genetic, isotopic, and lipid work to understand modern microbial processes. Ultimately, biomarkers can trace back the influence of microbes during extreme climatic events.

Expedition Hotchpotch
During the last week the central theme in our work was sea level change, but this week has come to an end and it is time for a change of subject. And a change of people too. At 7 o’clock this morning Pelagia arrived at Texel. All the non-Pelagia crew…

North Sea Expedition 'Sea level rise'
About 12.000 years ago sea level was more 60m lower than today and large parts of the North Sea were dry land. In the following 4.000 years sea level rose more than 40m and the North Sea was formed. This story currently lies buried below the present…

NIOZ@Sea: Black Sea cruise
This edition of NIOZ@Sea is a series of blogs from the Black Sea cruise of our scientists on board research vessel Pelagia. The Black Sea is the largest permanently stratified sea in the world. This is ideal to study the structure of microbial…
