Christian Andreasen

Christian Andreasen is an Associate Professor at the University of Copenhagen's Department of Plant and Environmental Sciences, where he leads the Plant Protection research group in the Section for Crop Sciences. He earned his MSc in Agronomy (1986) and PhD in Weed Science (1990) from the Royal Veterinary and Agricultural University (now University of Copenhagen). His academic career includes roles as Assistant Professor (1991-1995), Associate Professor (1995-present), and Head of Crop Sciences (2004-2015).

His research spans weed biology, sustainable crop protection, and seed technology, with emphasis on:

• Non-chemical weed control (laser weeding, thermal methods)
• Crop-weed interactions in changing climates
• Seed science and quinoa cultivation in tropical zones
• Biodiversity conservation in agricultural systems

Publications (2019-2025) demonstrate strong focus on sustainable agriculture technologies, particularly laser-based weed control, climate adaptation of crops, and biochar soil applications. Research consistently addresses herbicide alternatives, precision agriculture, and resilience of crops like quinoa under abiotic stresses.

He actively advises PhD candidates and has supervised 10+ doctoral projects. Major grants include Horizon 2020's WeLASER project (2021-2024) on autonomous laser weeding, AC/DC Weeds (2021-2022) for perennial weed management, and Sweedhart (2016-2019) on harvest weed seed control. Leads field and laboratory facilities at Taastrup Campus, collaborating internationally through NIBIO (Norway) and DanSeed consortium.
