Digital Equine Poor Performance: Is it pain related? (on-line)

Katrina Ask

is a researcher and university lecturer at the Swedish University of Agricultural Sciences (SLU). After earning her veterinary degree from the University of Copenhagen, she spent several years working in large animal practice and as an equine veterinary surgeon. She later completed a PhD at SLU on behaviors and facial expressions associated with equine orthopaedic pain. Balancing time between teaching and research, her ongoing research primarily focus on pain assessment in bovines and equines, and those behaviors and facial expressions linked to orthopaedic pain. Katrina further utilizes advanced objective gait analysis to study movement patterns during lameness in bovines and equines, and to explore the relationship between pain and movement asymmetry.
