Mathilde Hagens is a biogeochemist focussing on carbon and nutrient cycling in natural environments. She is interested in the functioning of both the terrestrial and oceanic carbon sinks in relation to climate change mitigation, with a particular interest in enhanced silicate weathering. She currently investigates this topic at the Soil Chemistry and Chemical Soil Quality chair group at Wageningen University & Research. Here, she leads the research line Soil Carbon Management and Climate Change, which is part of the Soil Science Cluster, and chairs the organising committee of the Wageningen Soil Conference 2023.

Mathilde's main research interests include:

• Carbon cycling in natural environments, and their driving factors;
• Biogeochemical transformations of carbon and nutrients in both the terrestrial and aquatic environments, and how these two zones are coupled;
• Comparing model output with in situ data as a tool for understanding carbon and nutrient cycling.

In her Ph.D. and postdoc projects Mathilde worked on the impact of biogeochemical processes on the carbonate system in the marine realm, for which she combined field data with numerical modelling.

• Towards carbon negative agricultural systems with improved soil functioning: an experimental study on the synergies between enhanced silicate weathering and biochar

• The role of earthworms in enhanced mineral weathering: understanding their impact on carbon dynamics and sustainable fertilisation

• Integrating biological and chemical soil processes to predict the climate-soil carbon feedback

• Member of the programme committee of Climate Studies
• Contact person for education of the Soil Chemistry and Chemical Soil Quality chair group
