Certified as a north american specialist in large animal internal medicine (by examination) Diplomate ACVIM 1988. PhD large animal physiology; University of Liege Belgium 1998. Professor equine internal medicine SLU 2000 to present.


Over the past decade has  focussed on infectious  diseases of the horse, including pathphysiology of european Anaplasma phagocytophilum, relationship of low  virulent viruses on health and athletic performance,  and on host pathogen   relationship of Streptococcus equi ssp zooepidemicus and Streptococcus equi ssp equi 


Has taught most topics in relation to large animals internal medicine concerning  equine and  ruminants in Canada, the USA.  Since relocating to Sweden teaching activities have been limited to topics largely related to equine  diseases.  Currently  teach in the 4th and 5th years of  the veterinary  program in the subject of clinical  diagnosis and responsible for expertise and  education in most of the infectious  diseases of the horse. Also serves as research supervisor and advisor, as well as examiner for final year  veterinary thesis projects. 


Currently completed a major  research team focus funded by FORMAS  to  investigate methods and understandings needed to eradicate the disease "strangles" caused by Streptococcus equi ssp equi from  horses populations in Sweden.




Member of the  Uppsala  Animal  Ethics  review  committee.  Member of  the Swedish Science Research  Council (VR)  expert  group  on animal Ethics. Founding member, and formerly   secretary and  board member of the European College of Equine Internal medicine;  currently  Ombudsman  for the  same college. 

Full member of the European Committee of Veterinary Education (ECOVE),  which is under the umbrella  of the The European Association of Establishments for Veterinary Education (EAEVE).

External  examiner for 8 PhDs outside of Sweden. Expert assessor internationally for 5  docenture/associate professorships (Finland, New Zealand, France) and 3 full professorships (Canada, Norway, Scotland).


Main  supervisor for eight succcessfully completed PhDs and  three as cosupervisor since 2000. Currently one cosupervised PhD candidate  due to complete late 2019.
