Present role
I’m an Ecological Engineer who is primarily helping farmers to manage their soils and field ecosystems. I have a problem-solving mindset, where I combine engineering, ecology and systems analysis. A lot of my work involves co-operation with farmers, farm advisors, and companies to apply research to practice (Research Extension approach). I have focused on a few key problems in the food system in the recent years (nutrient availability, soil structure, soil health, remote sensing, combining measurements with systems modelling).
I also participate in the sustainability assessment of renewable resource use and develop methods for managing productive ecosystems also in the future.
Research interests and expertise
- Soil management, soil health and field ecosystems
- Life cycle assessment (LCA), modeling of environmental impacts
- Soil carbon sequestration and nutrient cycling
- Food systems and production ecosystems
- Systems analysis, mathematics, and quantitative uncertainty assessment
- Climate change adaptation and mitigation in agriculture
- On-farm research networks (Carbon action)
Current projects
STN MULTA: Multi-benefit solutions to climate-smart agriculture (2019-2025)
Evergreen revolution with Cover Crops – best practices to enhance carbon sequestration (2021-2023, results are still published)
Novel soil management practices – key for sustainable bioeconomy and climate change mitigation (SOMPA) (-2023, results are still published)
Publications
I have published over 40 peer reviewed scientific articles, in addition to book chapters and extension reports. The latest 4 are here, the rest are in @GoogleScholar and on the University repository as well as in Zenodo (datasets and code).
