Leg. vet. DVM, PhD-student

I finished my Master of Science in Veterinary Medicine in 2012 and in the same year started my PhD-education within the Future Animal Health and Welfare Initiative at SLU. I am particularly interested in obesity-related metabolic dysfunctions in dogs, which is also the topic of my PhD-project. I also enjoy working with students and currently I teach anatomy at the Department of Anatomy, Physiology and Biochemistry, SLU.
Obesity is a groing problem in dogs
People in the world are growing more and more obese and welfare diseases associated with our lifestyle are becoming a big problem. Even our companion dogs that share our lifestyle are becoming more obese; in fact up to 50% of our dogs today are overweight.
The overweight dog has an increased risk of reduced wellbeing, earlier onset of chronic diseases and a shorter life and I believe each one of these consequences motivates obesity research in dogs. The metabolism in dog besity is not as thoroughly investigated as in humans and we need a better understanding of metabolic alterations in overweight dogs for futher development of therapeutic methods.
The overall goal of the PhD-project is to investigate obesity-related metabolic dysfunctions in dogs using serum, plasma, and urine. Privately owned healthy intact male Labrador retrievers with different body contitions (i.e. from lean to overweight) have been sampled before and after a standardized meal.
