I am Professor of Large Animal Surgery at the Swedish University of Agricultural Sciences at Uppsala. I perform experimental and clinical research in the large animal clinic, including retrospective studies on clinical efficacy, with an overall aim of development effective surgical methods documented by objective clinical methods.


Surviving Surgery!

I have spent a great deal of the last 30 years in surgery theaters doing surgery on horses, cows and pigs, teaching and researching within my favorite topics – trauma, inflammation and pain.

During these years, I have nurtured a broad international network. As a result, I am currently supervising a number of projects in Sweden and Denmark related to topics of pain and inflammation: including tendon sheath pathology in horses; objective lameness and ataxia scoring in horses; and pain score systems in cattle and horse, including pain faces.

As a result of my work with pain faces, my latest international project investigates the possibility of a new approach of screening for pain in horses: using automated decoding of facial expressions via video films. My collaborators in this endeavor are leading computer vision scientists from the Machine Learning Lab at University of California in USA. They have developed machine learned technology for automated decoding of human expressions of emotions, including pain. For our interdisciplinary project, we will produce a set of videos including horses with and without pain. These videos are then subsequently used to “train” a machine learning system to discriminate between horses in mild to moderate pain, and horses without pain. This project may also open the road for automated recognition of pain in a number of other relevant species, including cattle, swine and rodents.

In addition, in close contact with my SLU colleagues Marie Rhodin and Elin Hernlund, I also collaborate on additional research projects that include veterinarians at the Dept. of Equine Sciences at Utrecht University as well as engineers at the Robotics, Perception and Learning Dept at KTH in Stockholm.


Pregraduate: Lectures, practicals and examination in most subjects in the large animal surgery curriculum for veterinary students.

Postgraduate: Lecturer at courses and seminars on inflammation, intensive therapy and traumatology for practicing veterinarians, the Education of Equine Veterinary Specialists, Copenhagen and Ph.D. Courses.
