About me

I am an assistant professor in environmental science with a background in geology. I studied paleontology, and paleoclimate with an emphasis on chemical proxies. At SU, I focus on (aquatic) carbon biogeochemistry. My group targets sensitive regions to climate change such as the Arctic and tropical wetlands. Currently,  I work on several projects:

- Reconstructing (past) methane production and oxidation in the Canadian Arctic. I use sediment cores and molecular proxies extracted from them (as well as bulk organic matter), with the help of modern studies

  • Tracking the effect of glacier melt in Greenlandic fjords:
  • Carbon cycling in the Okavango Delta, and the effect of drought on carbon export and burial
  • Mackenzie River monitoring, supporting long-term monitoring of particulate organic carbon and its isotopes in a project led by AWI Potsdam 
  • Arctic terrestrial carbon, from source to sink (projects PeCaBeau, FLO CHAR)
  • Investigating methane emission from aquatic systems: What happens to coastal lakes when sea-level rises?

The team: 

Lukas Bigler: PhD student "Effect of glacial meltwater on East Greenland fjords"

Joshua Hellman: Master student "Transgression and Transformation: Methane Cycling in Thawing Arctic Coastal Landscapes"

Thijs Vink: Master student

I'm happy to discuss potential bachelor and master thesis projects. Some examples: "Carbon content and sources in the Last Ice Area", "Linking organic carbon burial, vegetation, and fires".

If you are interested in writing a Marie-Curie Fellowship and being hosted at SU, contact me.

2025 summer sampling in Tuktoyaktuk

I teach during the master in atmosphere, biogeochemistry and climate:

- I am the course coordinator for MI7023 (Laboratory method in environmental sciences), and MI8017 (Environmental biogeochemistry):

- Environmental biogeochemistry: we will talk about carbon dynamics in a changing world,

-Laboratory method in environmental sciences: you will design and run your own experiment(s),


- Environmental field studies: we will sample freshwater and marine environment.

Collaborations at SU:


GREENCARB

Climate change is speeding up glacier melt, releasing methane and carbon into oceans. This leads to CO₂ release via mineralization, contributing to acidification and greenhouse gas emissions. To predict carbon flux impacts on ocean chemistry, we need baseline data on the fate of this material.

Tracing how Atlantic Water impacts North Greenland: THAWING

THAWING is an interdisciplinary research project investigating how warmer Atlantic waters affect glaciers, sea ice and marine ecosystems along the northern coast of Greenland. Using expedition data and long-term sediment records, the project examines changes in the Arctic’s so-called Last Ice Area in a climate perspective.
