I am interested in improving organic and agroecological production systems by investigating the relationship between plant characteristics and cropping systems. I work with traditional varieties of cereals and legumes to find phenotypes and unique traits relevant for arable organic production and intercropping systems. The last years I have focused on legume-legume intercropping of faba bean and pea. Besides the agronomic aspects I am interested in the full value-chain of traditional and niche varieties – from seed and seed systems to the quality and culinary attributes of the grains that end up on our plates. 

On-going:

Peas of the North (PEANORTH). An Agroecology Partnership project in the Baltic-Nordic region that stretches across the entire value chain of traditional pea varieties – exploring historical and contemporary seed systems, phenotypical plant characteristics, arable production in intercropping, and culinary and quality traits of the grains.

Utilising crop diversity of cereals, pea and faba bean for organic intercropping systems. Funded by Ekhagastiftelsen.

DIVINFOOD (WP2, WP3, WP4). An EU Horizon project working to explore and promote the use of neglected and underutilised crops (NUCs) to increase the diversity of the food that we eat.

Finalised:

Intercropping traditional pea varieties with faba bean in organic farming: Legume diversification for sustainable agriculture. PhD project investigating intercropping of faba bean and pea. Funded by Ekhagastiftelsen, Behms Fond, Martha and Dagny Larssons fond, and the Dept. of Biosystems and Technology (SLU). 

Legumes varieties for organic production in the Nordics. Pilot study funded by Naturastiftelsen.

Heritage varieties and the extreme weather 2018 - how did it go? Pilot study funded by SLU FutureFoods.

Organic cereal breeding and diversity facilitation. Pilot study funded by Naturastiftelsen.

I supervise BSc, MSc and internship students and contribute with individual lectures related to organic plant breeding, crop diversification and conservation and development of plant genetic resources to the Advanced Plant Breeding and Genetic Resources (BI1407) course and courses in the Agroecology master programme at SLU Alnarp.
