Head of the department for Agriculture and Environmental Engineering, which works with research and development for sustainable agricultural and circular economy companies in practice. With deep expertise, unique infrastructure and a broad partnership with industry players, we work actively to ensure that research is scaled and used in real operation, and that project results and data are transformed into knowledge that is put to use. The department has a unique ability to take concepts all the way from idea to product, among other things by having our own workshop where we can transform abstract thoughts into real prototypes that can be tested and evaluated in practice. In addition to management and responsibility for the department's overall operations, I work partly as a project manager and technical expert in biogas production and adjacent systems.
