I am a postdoctoral researcher of animal nutrition. My PhD studies were focused on ruminant nutrition and modelling. My current research is focused on insect nutrition and feeding.


Research goals:

My research has always been focused on reducing environmental impact from animal production thru improved feeding efficiency and improved production systems.

Current project:

Äta insekter – en smaklig lösning på dagens globala problem
Project leader - Anna Jansson


Previous projects:

New feed protein model for ruminants with 15N labelled feeds - a tool for reduced N emissions
Project leader - Pekka Huhtanen

Improved protein quality in home grown feeds by heat treatment
Project leader - Mårten Hetta

Nutrient supply and productivity in organic forage and milk production - improved forage production and utilization based on local resources
Project leader - Havard Steinshamn
