My main research interests are nutrition and exercise physiology in animals kept for sports and companionship.
Currently course leader and lecturer at two courses at masters level within exercise physiology and rehabilitation of sport- and companion animals. Gives lectures and demonstrations at undergraduate level within anatomy and digestion physiology.
Ongoing research projects:
No hoof no horse? - A study on quality of hooves of Standardbred trotters. Responsible: Anna Jansson.
Landscape preservation by grazing Gotlandsruss ponies. Responsible: Anna Jansson and Carl-Gustaf Tuhlin
Effect of different feed composition on satiety regulation in dogs. Responsible: Johan Dicksved, PhD-student: Hanna Palmkvist
