Short presentation
My research research centers on land use changes in long temporal perspectives. I work between agricultural and environmental history with a special interest in planning policies, infrastructure and the role of public administration.
DFF-International Postdoc Project 2024-2026.
My current project "Dry Lands, Wet Soils" is financed through the Independent Research Fund Denmark. The project investigates the legacy of early 20th century soil improvement scheme on later agricultural policies and landscapes. This project analyses the historically contingent ideational and material barriers to the current calls for wetting agricultural peat soils.
Methodologically and theoretically, I am inspired by actor-network-theory, in particular relational approach to what, whom and how both human and non-human actors matter in certain places at certain times.
Currently, I am also engaged in the transdisciplinary living lab “Land use change for the Green Transition” funded by the University of Copenhagen Green Solutions Centre. The living lab aims at understanding and proposing holistic solutions for land use change in former wetlands. In transdisciplinary work I am particularly interested in how historical knowledge can inform better policy decisions.
In 2024-2025 I am a guest researcher at Department of Human Geography, University of Stockholm.
