Dr Alvaro Wehrle Martinez MVS, PhD

Senior Lecturer - Veterinary Science

School of Veterinary Science

Dr Alvaro SeBastian Wehrle Martinez is a Senior Lecturer in Veterinary Pathology at Ƶ’s School of Veterinary Science. His expertise includes connective tissue pathology, particularly of bone and joints, as well as reproductive and haemolymphatic pathology. His PhD investigated the pathogenesis of spontaneous humeral fractures in New Zealand dairy heifers. He is currently researching intervertebral disc disease (IVDD) in cats, among other interests. A two-time recipient of the BVSc Teaching Award, Dr Wehrle is ACVP board-certified and passionate about complex diagnostic cases, anatomic pathology, and collaborative research and teaching.
