Dr Jimena Yapura DVM, MSc, PhD, FHEA

Senior Lecturer in Anatomy and Physiology - Animal Reproduction

Doctoral Supervisor
School of Veterinary Science

Jimena is a Lecturer in Veterinary Anatomy and Physiology, with expertise in Animal Reproduction. She completed her veterinary medicine degree in Argentina and obtained her MSc and PhD in Veterinary Biomedical Sciences at the University of Saskatchewan, Canada.  During her graduate program she focused on the development of oestrogen-free approaches for the control of oestrous cycle in cattle but has a great interest in comparative reproductive biology. Her current research projects include cattle, pigs, and cats.
