Innovation, Industry collaboration and Technology Transfer

Since 1998, I have been the principal researcher developing the SimHerd model. This founded in 2010 the spin-off company ‘SimHerd A/S’. The model is widely used by veterinarians and consultants in several countries.
Starting 2010, I have been responsible for the development of the herd health analytical tool ‘Kvartalsrapporten’ together with Dyrelæger & Ko, who is now using it as their key tool in half of Danish dairy cattle herds.
HerdNavigator. I participated in the Biosens 1 & 2 projects, which developed the scientific background for the biological part of HerdNavigator tool. The companies Foss, Lattec and DeLaval participated in the projects.
SEGES tool. I have had collaboration with the farmers’ organization, SEGES, through research and development projects providing tool for feeding level optimization, reproduction management analyses and tools, lactation curve analyses, and Animal Health Economy analyses.
