Emil Olsen
Neurologist and Equine Internist at the Veterinary Teaching Hospital in Uppsala (Universitetsdjursjukhuset)


Clinical Degrees:
American Specialist (Diplomate) in Large Animal Internal Medicine
European Specialist (Diplomate) in Equine Internal Medicine
Residency trained (ACVIM) in Neurology

Research Degree:
Ph.D.: Objective and Subjective Assessment of Equine Ataxia


A passion for evidence-based large animal internal medicine combined with experience in first-opinion and referral practice led to a Ph.D. funded by the University of Copenhagen, located in the acclaimed Royal Veterinary College’s Structure & Motion Lab followed by the clinical training of my dreams in 2013 as a large animal internal medicine Resident at Cornell University Hospital for Animals and from 2014 a dual residency in large animal internal medicine and medical (95% small animal) neurology.
