Kelly Yarnell

Principal Lecturer

School of Animal Rural & Environmental Sciences

Staff Group(s)
Animal and Equine


Dr Kelly Yarnell lectures on the BSc Equine Sport Science, BSc Equestrian Psychology and MSc Equestrian Performance Health and Welfare degrees in the areas of

  • Anatomy and physiology
  • Research skills
  • Equine Sports injury
  • Issues ethics and welfare
  • Equestrian performance

She is also the equine dissertation module leader

Dr Yarnell is also research active and currently has externally funded projects in the areas of animal biosecurity, equine welfare, ophthalmology and equine sports physiology.

Career overview

Dr Yarnell originally trained as a veterinary nurse before studying for a BSc in Equine and Human Sport Science. She then worked as a welfare executive for the British Horse Society before being awarded a Vice Chancellor's Bursary to undertake her PhD study here at NTU. Dr Yarnell has worked as a teaching fellow in the School of Veterinary Medicine at Nottingham University before returning to NTU to take up a full time lecturing position.

Research areas

Recent and ongoing projects are in the following areas;

  • Adrenal assessment in domestic and free ranging equids
  • Microbiology and Biosecurity in the Equine species
  • Impact of housing design on equine welfare
  • Polocrosse
  • Equine Ophthalmology
  • Infrared thermography (IRT) as a tool to monitor the physiological response to stress horses

Sponsors and collaborators

  • BEDMAX currently provide funding for Kelly’s PhD student and recently funded an additional equine biosecurity project.
  • Chester Zoo – Funder and Collaborator on several ongoing projects investigating the development of adrenal assessment in the equine species (domestic horses, zebra, onager) with regards to sampling protocols, field technique development and assay validation.
