Dr Janine Donaldson is a lecturer in the School of Physiology at the University of the Witwatersrand, South Africa. Her primary research interest is the gastrointestinal tract (GIT) and the GIT accessory organs, the liver and pancreas, in both normal and diseased states. In understanding the normal physiology of the GIT, liver and pancreas as well as the progression and pathogenesis of various diseases within the GIT and its accessory organs, will enable the development of new, improved therapeutic strategies for such diseases.

Another one of her primary research interests is that of the measurement of erythrocyte osmotic fragility in various mammals and bird species. The measurement of haematological parameters, such as erythrocyte osmotic fragility, is an important clinical tool for the assessment of the overall health status of the animal. Erythrocyte osmotic fragility can be affected by various extrinsic and intrinsic factors. The effects of factors such as the consumption of a high-fat diet as well as oxidative stress on the ability of the erythrocytes to resist osmotically-induced haemolysis are currently being investigated within her research group.
