Research 
My research explores plant–soil interactions across the diverse bioclimatic zones of Switzerland, with a focus on the processes driving soil formation and evolution. I study the complex ecological relationships that link above- and below-ground components of terrestrial ecosystems, particularly how biotic and abiotic factors influence soil functions and services over time and across environmental gradients.

I am particularly interested in:

  • Soil development and organic matter dynamics across elevation and climate gradients
  • The role of plant-derived phytochemicals in litter decomposition and humus formation
  • Long-term soil property changes, including legacy effects from past land use and management
  • Contributions of microbial and faunal communities (e.g., nematodes) to ecosystem functioning in mountain soils
  • The impact of solar radiation and other climatic drivers on decomposition and soil processes in alpine environments

Ongoing projects
2025
Terres vivantes project, in collaboration with Porf. Claire Le Bayon and Sarah Rey – Finalization of the project and presentation of results.

2024-2025
Artemisia absinthium project, Botanical garden of Neuchâtel in collaboration with the functional ecology laboratory of the University of Neuchâtel – Collection of soil samples and soil laboratory analysis.
