Research
My field of expertise is pollen analysis and vegetation history, with a foundation in botany and archaeology. My work highlights how human activity over time has shaped vegetation, biodiversity, and landscapes. The research combines field studies of present-day vegetation with pollen analyses from lake sediments, peat bogs, and archaeological contexts. I am particularly interested in quantitative landscape reconstructions, methodological aspects of pollen production, and pollen in archaeological contexts, as well as how the introduction of agriculture and the development of cultural landscapes have influenced the natural environment. Interdisciplinarity is a key aspect of my research, where collaboration with archaeologists and a broad international network contributes to a deeper understanding of the past as a basis for managing today’s cultural and natural environments.
Examples of research areas:
- Relationships between modern vegetation and pollen deposition to enable quantitative reconstructions of past vegetation
- Methodological factors influencing estimates of pollen production used in reconstruction models
- Landscape reconstructions at different spatial scales
- The introduction of agriculture and the development of cultural landscapes with infields and outfields
- Understanding prehistory as a basis for managing natural environments
- Food, food production, and trade in prehistoric times and the Middle Ages

Projects
I am work package leader and the initiator of the University Museum’s application for funding to establish a Centre of Excellence (SFF), led by Haakon Fossen. The center is called Center for integrated Earth–Society Dynamics (ESD), a curiosity-driven initiative to fundamentally advance the science of human-environment interaction. The idea is to break down the boundaries between Geoscience, Biology, Archeology and Anthropology to create a novel transdisciplinary framework in which we aim to understand how today’s society has been built upon a foundation shaped over geologic time, to decode the interactive mechanisms behind natural and societal changes over the past 10,000 years, and to use this insights to build actionable scenarios for the future.
