About me

Dr Greer is an epidemiologist, medical researcher and veterinarian who has been involved in clinical research, academic teaching and practice for over 25 years. She completed her Bachelor of Arts majoring in Pure Mathematics in 1972, Bachelor of Veterinary Science in 1979, Master of Veterinary Science in 1995, PhD in the School of Medicine, The University of Queensland in 2004, and membership of the Epidemiology Chapter of the Australia and New Zealand College of Veterinary Scientists in 2005. Her areas of research interest include Congenital Hyperinsulinism of Infancy, bone metabolism in Cystic Fibrosis, Vitamin D in Type 1 Diabetes, as well as study design and data analysis. These latter interests have led to collaborations with clinicians and scientists in a wide variety of fields of research, for example human viral respiratory infection, paediatric liver disease, Pseudomonas spp infection in humans and horses, and many others. Since 1990, Dr Greer has been variously a lecturer and researcher with The University of Queensland School of Medicine, Queensland Children’s Medical Research Institute and affiliated institutions, and taught epidemiology in the School of Veterinary Science where she inaugurated the first course in research methodology for postgraduate students.
