Biography

Academic memberships: Registered Veterinarian with the Council of Veterinary Surgeons of Zimbabwe (CVSZ). Member of The Physiological Society of Southern Africa (PSSA).

Joseph qualified as a veterinarian in 1991 from the University of Zimbabwe, and registered with the Council of Veterinary Surgeons of Zimbabwe. In 1992, he joined the staff development programme at the UZ as a temporary lecturer in physiology until May 1993, when he was awarded The Beit Trust Fellowship and enrolled for postgraduate studies in Physiology at The University of Liverpool, UK. In July of 1997, he was awarded the PhD degree and the title of the thesis is, ‘Transmural differences in control of contraction in rabbit left ventricular muscle’. In January 1997, he returned to the University of Zimbabwe to become part of the lecturing staff in Preclinical Veterinary Studies department until March 2004. From October 1997, he was appointed Head of Pre-Clinical Veterinary Studies for 4 years until September 2001. From 1st of March 2003 to March 31st 2004, he was appointed as Deputy Dean of the Faculty of Veterinary Sciences at UZ. On the 1st of April 2004, he joined the University of Pretoria as a Senior Lecturer in the Physiology section of the Department of Anatomy and Physiology, Faculty of Veterinary Science, Onderstepoort Campus. In 2007, he enrolled for the Postgraduate Certificate in Higher Education with the Faculty of Education, University of Pretoria, which he completed in the same year. He was appointed as the Acting head of the department of Anatomy and Physiology on 1 November 2017, and as the substantive Head of Anatomy and physiology for a 4 year term, and promoted to associate professor on the 1st of September 2018. In 2022 this was renewed for another 4 year term, which is current.

Research Interests
Joseph now focusses on the following research areas: nutrition, metabolic syndrome, GIT and wildlife. Currently he is working on heat stress in broiler chickens and use of probiotic, Saccharomyces cerevisiae and ascorbic acid as exogenous antioxidants in mitigating the adverse effects of heat stress. A PhD student is in the final year on this project and should be graduating next year with a few publications from this study. My second project is on, 'The effects of nutritional stress and reproduction on stable isotope ratios of ruminants, monogastric, and hind–gut fermenters in South Africa'. Another PhD student is on that project as well which is at the ethical clearance stage. Previously, I worked on the characterisation of the fat body and other adipose tissues of the Nile crocodile (Crocodylus niloticus), on which project a PhD student graduated in September 2017. The next part of the project envisages interrogating the more than 70 up-regulated genes in pansteatitic tissue. The aim is to get to the individual proteins that are produced by the up-regulated genes to be able to assign pathophysiologic function - key to the mechanism(s) of pansteatitis. This part is still pending due to financial constraints.
