Resident in Veterinary Neurology


  • BSc
  • BVSc
  • PhD

Jon graduated from the University of Bristol in 2013. After a brief period working in South Africa, he returned to the UK and worked in mixed vet practice for 18 months. He subsequently completed a 1-year rotating internship in Small Animal Medicine and Surgery from 2015-2016.

Jon developed a research interest in spinal cord injury and completed a PhD in regenerative medicine and neuroscience at the University of Bristol in 2019 investigating modified olfactory ensheathing cell transplantation. He subsequently spent 2 years at the Royal Veterinary College as a postdoctoral researcher working to develop an “intelligent neuroprosthesis” to manage incontinence after spinal cord injury. He started at Highcroft Referrals as Resident in Neurology in July 2022.
