I am responsible for the crop and crop managment parts of the Agricultural cropping system unit at the Department of Crop Production Ecology. I am Vice Dean of Agricultural Sciences at the Faculty of Natural Resources and Agricultural Sciences (NJ), member of the Faculty board, chairman of the SLU Cropping System Platform, chairman of the Field Research Unit, a joint venture between SLU and stakeholders in agricultural field research, and chairman of the Management board for long-term experiments.
I teach at all levels on courses related to crop production ecology on topics such as crop production in relation to environmental conditions, cereals, competition in short lived plant stands, crop rotations, cropping systems etc. I am the main supervisor of four PhD students and assistant supervisor of another two.
I do research un subsidiary crops and their functions in cropping systems, particularly in the context of the need to develop cropping systems that are adapted to and help mitigate climate change, are less dependent on chemicals to preserve their function, reduce risk of polution, as well as enhance and take benefit from biodiversity. I also do reserach on crops and how to growth them for increased ecological and economical value. The research takes advantage of the knowledge farmers have and test hypotheses in experiments that are evaluated from an agronomical, food science and social science (consumer testing) perspective. A third topic is based on knowledege collected at farms and in long term experiments and investigate the importance of climate and managment for the production of ecosystem services, mainly those relating to production. A fourth topic investigate plant traits and how they interact with managment and the environment. I am highly dependent on researchers from other disciplines to conduct my research, e.g. researchers in ecology, soil science, social science, plant pathology, food science.
I am the main supervisor of PhD-students Elsa Lagerquist, Tove Ortman, Steffen Dahlke and Miguel Romero, and assistant supervisor of Do Van Hung and Rafaelle Reumaux. The following PhD-students gained their PhD degree under my supervision: Tarirai Muoni (2019, assistant supervisor), Moritz Reckling (2018, main supervisor), Raj Chongtham (2016, assistant), Björn Ringselle (2015, assistant), Linnea Asplund (2014, assistant), Shakhawat Hossain (2013, assistant) och Lena Engström (2010, assistant). Post docs under my supervision: Pierre Chopin (2017-2020), Marcos Lana (2017-2019) and Björn Ringselle (2015-2017).
