about me
I am a researcher investigating the links between carbon & nutrient cycles and how we can apply this knowledge for sustainable land use. My main tools are computer models which valorize ecological theory, machine learning, and observations from various sources. Focus areas are the tropics, enhanced rock weathering, phosphorus cycling & plant-soil interactions.
I currently lead the BIOGEO team, coordinate the C-ROCK project, and develop the SPINacc land surface model accelerator & phosphorus cycle of the ORCHIDEE land surface model. I am also a member of the scientific steering committee of the CLAND Convergence Institute and the core ORCHIDEE developer team.
My work is guided by a strong commitment to open access of scientific knowledge.
research topics
Phosphorus limitations
Soil phosphorus availability is often low – affecting plant functioning in a wide range of ecosystems with far reaching implications for the carbon cycle and climate (e.g. Goll et al. 2012). A focus of my work is the assessment of ecosystem responses to man-made changes in atmospheric carbon dioxide concentration, climate and aerosols (e.g. Goll et al 2022). Further, I am investigating the associated feedbacks between land biosphere and the climate system which control the pace of man-made climate change (e.g. Goll et al. 2014). Contributing to multiple international projects such as RESCUE & CALIPSO among others.
Management solutions
Phosphorus rocks are the basis of conventional fertilizer, but are a limited and unevenly distributed resource. The demand of fertilizers is expected to increase in order to fight hunger and climate change (Li et al 2021). Alternative resources and solutions for improving soil fertility are being explored for transitions towards sustainable resource use. A focus of my work is the use of soil management measures, alone and in combination with other land uses, for sustainable biomass production and greenhouse gas removal (e.g. Goll et al. 2021). I am coordinating the C-ROCK project on ‘Soil responses to enhanced rock weathering’ and contributing to projects such as Clarity .
