My overall research interests lie within cropping systems ecology and are directed to 1) the diversification and multifunctionality of arable crops and cropping systems and 2) the increased use of legumes for sustainable food systems. In order to meet these objectives I strive to use agroecological approaches based on participation with farmers and other stakeholders, systems thinking, ecological principles and multidisciplinary research. More specifically, my research includes studies of ecosystem services provided by diversified cropping systems, incentives and obstacles related to the cultivation and use of legumes as human food sources, factors that influence symbiotic nitrogen fixation, nitrogen dynamics in the rhizosphere and at the cropping system level, and sustainable management of sown species-rich grasslands for biodiversity and bio-energy.
I am engaged in the department's teaching in the Agroecology, Horticultural Science, Horticultural management, and Agricultural and Rural Management programs, via course management and lectures lectures about crop production, symbiotic nitrogen fixation, nutrient cycling in cropping systems and roles of legumes for sustainable production systems.

I interact frequently with the Swedish agricultural sector (farmers, advisors, food companies, the Swedish Board of Agriculture, the Nordic Genetic Resource Center, Regional County Boards) in questions about cultivation and use of legumes and enahnced sustainability of crop production. I also have a large scientific network, and I collavorate woth researchers at several departments at SLU as well as at other Swedish and international universities and research institutes.
