Biogeochemist interested in Carbon cycling in ancient, recent and future ecosystems. I use and develop straight forward lab methods using biomarkers and isotopes. I like the combination of lab and field work together with education of students.
Our latest publication relying on a collaboration between Universities of Zurich and Kiel highlights the usefulness of a screening tool like DRIFTS to disentangle organic matter and mineral changes in Jurassic sediments for poaleoenvironmental assessment. www.sciencedirect.com/science/arti...
Paleoenvironmental assessment of a lower Jurassic succession in the NW-German Basin employing DRIFTS
High-resolution reconstruction of paleoenvironmental conditions of sedimentation requires the qualitative and quantitative assessment of the major sed…

Great new study led by Charlotte Angove and supported by @snsf-ch.bsky.social @erc.europa.eu and others on d2H isotope composition in alkanes and carbohydrates to decipher there environmental significance for paleoenvironmental studies. nph.onlinelibrary.wiley.com/doi/10.1111/...
Time‐integrated δ2H in n‐alkanes and carbohydrates from boreal needles reveal intra‐annual physiological and environmental signals
Reliable insights from key δ2H bioindicators, n-alkanes and carbohydrates, are hindered by our limited understanding of isotope fractionation processes related to leaf water and primary assimilates....

Great collaboration between Spatial Genetics and Soil Biology and Biogeochemistry groups @UZH studying drought responses of beech saplings in terms of chemical and spectral properties of their leaves. You want to know more? Just have a look... agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Leaf Spectroscopy Reveals Drought Response Variation in Fagus sylvatica Saplings From Across the Species' Range
Leaf reflectance measurements effectively track drought-induced trait changes in beech saplings in a non-destructive way Beech saplings from the Iberian Peninsula show greater drought resistance ...

Had just a great defence of my PhD student Tatjana Speckert, who conducted her research in the @SNSF funded #IQ_SASS project @UZH. I am looking forward on the next couple of months, when she can complete some of her studies as a Postdoc in my group…

Fresh out of the press: Comparison of paleobotanical and biomarker records of mountain peatland and forest ecosystem dynamics over the last 2600 years in central Germany. This great research was funded by @snsf_ch and conducted @uzh_geo @UZH_en: bg.copernicus.org/articles/20/...

"Source or decomposition of soil organic matter: what is more important with increasing forest age in a subalpine setting?" we asked in our @SNSF funded #IQ_SASS project @uzh_geo @UZH_en. Here, you can find the answer: www.frontiersin.org/articles/10....

Check out our latest publication on carbon cycling in a subalpine 130-year-old afforestation sequence at #Jaun (FR, CH). The reserach was conducted as part of the #SNSF funded #IQ_SASS project at Department of Geography at University of Zurich: soil.copernicus.org/articles/9/6...
