I received my PhD degree in 2012 at SLU with the thesis entitled ”Effects of increasing the proportion of high-quality grass silage in the diet of dairy cows”. The thesis examined the effects of increasing the proportion of high quality grass silage in diets of dairy cows over the entire lactation. The results showed that gradually increasing the dietary proportion of silage reaching upp to 70 % on dry matter basis in late lactation did not significantly affect milk yield compared with feeding 50 % silage. Positive effects of the higher proportion of silage were shown in terms of profitability and milk fatty acid composition. Since my dissertation I have worked as researcher and teacher at the department of animal nutrition and management with focus on ruminant nutrition, mainly dairy cows.
My research interests include ruminant nutrition: forage utilization, feed efficiency, environmental impact and sustainable use of feed resources and sustainable animal production systems. I am also interested in research questions regarding future food systems and how these can provide animal products in a sustainable way.
To investigate and evaluate different strategies for increased sustainability in animal production; including feeding, milk and meat production, environmental impact and animal welfare.
Animal science, ruminant nutrition, experienced in the design of large animal experiments. Worked with sampling in rumen-cannulated cows and performed gas-sampling using the Sulfurhexafluoride tracer technique in dairy cows, experienced in milk fatty acid analysis. Interpretation and analysis of small and large data-sets, scientific writing.
Activity with stakeholders outside the scientific society
I received a scholarship from the King Carl XVI Gustaf 50th Anniversary Fund for Science, Technology and the Environment in May 2014. The scholarship enabled studies on environmental impact from dairy production through life cycle assessment (LCA) and the transformation from human-inedible feed (e.g. grass and by-products) to high-quality proteins in milk and meat.

My current research is about how dairy cow longevity and recruitment strategies affect methane emissions at herd level. I also participate in a project that examines indicators for ecosystem services in dairy farms. A new project that recently started is about the effects on methane emissions of dairy cows when fed a feed supplement of red algae.
