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:
- GREENCARB will sail to East Greenland on board RV Skagerak in August 2026,
- Past campaigns: 2025 campaign
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?

New publications:

-Distribution and sources of organic matter in submarine canyons incising the Gulf of Palermo, Sicily: A multi-parameter investigation. Biogeoscience.

-Biomarker 14C evidence for sources and recycling of pre-aged organic carbon in Arctic permafrost regions. Geochimica and Cosmochimica Acta.

-Mineralogy as a potential driver of irregular radiocarbon patterns among Icelandic riverine carbon pools. Environmental Research Letter.

The team:

Lukas Bigler: PhD student

Joshua Hellman: Master student

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".

Education//career path:

2024-2025: Group leader University of Basel

2019-2024: Postdoc at ETHZ

2019 PhD in organic geochemistry/paleoclimate at Utrecht University/NIOZ

2014 MSc. in geology at U. Lyon 1/ENSL

2012 BSc. in geology at U. Lyon 1/ENSL

Teaching

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.

Research

Collaborations at SU:

- Sofi Jonsson: Link between heavy metals and organic matter in permafrost

- Flor Vermassen: Effect of melting glaciers on Greenland fjords - See Atka project

- Johan Ström: Effect of melting glaciers on Greenland fjords - See Atka project

- Matt O'Regan: Organic carbon burial on the Beaufort Sea, modern and past perspective
