Veterinary Program Director

About me

I am a South African-born and trained veterinarian and specialist in veterinary reproduction. I spent most of my career at the University of Pretoria, with brief stints in practice in the UK and South Africa and in academia in the USA. My current role is mainly in administration of the veterinary program, involving oversight of curriculum delivery and development, student and international affairs.

Teaching area

DVM projects: I coordinate the VET616 unit, a core component of the curriculum which incorporates research skills training and the completion of a research-based project during the last 2 years of the course.

I also teach veterinary reproduction as part of the Reproduction & Obstetrics (VET463) and Theriogenology (VET637) units.

Research areas

Veterinary education: Curriculum design and development, the role of student research projects in veterinary education

Animal reproduction: Bovine and ovine breeding potential, uterine immunity, pregnancy diagnosis, assisted reproduction technologies and infectious diseases associated with reproductive function. Wildlife reproductive evaluation, clinical management and assisted reproduction technologies.
