Justin is a Lecturer in Equine Surgery at the Royal Veterinary College (RVC). He holds the RCVS Certificate in Equine Surgery (Soft Tissue), the ECVS Diploma in Large Animal Surgery and is a European Specialist in Large Animal Surgery

Justin graduated from the RVC in 1997 and completed a Junior Clinical Training Scholarship at the RVC in 1998. He then completed 3-year Senior Clinical Training Scholarship in Equine Surgery and Masters of Science at the University of Edinburgh and Auburn University, U.S.A. He worked as a lecturer in Equine Surgery at University College Dublin, Ireland before returning to the RVC in 2003 as a lecturer in Equine Surgery.

Justin’s current research includes new surgical techniques for laryngoplasty and paranasal sinus surgery in horses

  • Bioelectronics

    Bioelectronic medicine, or electroceuticals, is a rapidly developing therapeutic field in which biomedical devices are used electrically to block, record, or stimulate neural activity as an alternative to drugs.

    Pharmaceutical and surgical intervention are not always as effective as we would like or desirable, especially in species that are extremely sensitive to drugs, such as horses. Bioelectronic medicine allows us to intervene to help patients without the risks associated with other interventions.
