James Warland

Head of Internal Medicine

RCVS Recognised Specialist in Small Animal Internal Medicine
European Specialist in Small Animal Internal Medicine


James graduated from the University of Cambridge in 2009, before working in mixed practice in Bedford, where he developed an interest in small animal medicine and oncology. He returned to the Queen's Veterinary School Hospital (University of Cambridge) as a Junior Clinician in Oncology before undertaking a three year residency in internal medicine, which he completed in 2015. He was awarded his ECVIM diploma and specialist status in 2016.

He worked in referral practice at the Animal Health Trust, Newmarket, from 2015-2017 before undertaking a Wellcome Trust funded PhD at the Stem Cell Institute/Department of Haematology at the University of Cambridge. His PhD research focussed on the use of induced pluripotent stem cells to make megakaryocytes, which are the cells in the bone marrow that produce platelets for blood clotting. In the future, this approach could allow us to produce blood transfusions that can be grown in a lab, without requiring a donor. Although most of his PhD focussed on human cells, he hopes that the same technology can be used to develop transfusions for dogs and cats.

James also volunteers for the British Small Animal Veterinary Association (BSAVA) and currently sits on their national Council and Scientific Committee. He is an Associate Lecturer in Small Animal Internal Medicine at the Department of Veterinary Medicine at the University of Cambridge.

James enjoys all aspects of internal medicine, but is particularly interested in haematology and immune mediated diseases.

Outside of work he enjoys travelling, although this has recently been curtailed by his young family, who now occupy most of his spare time! He has a particular affection for bearded dogs, and shares his home with an Irish terrier called Albi.
