BApSc(Ag)(Hons) PhD

Susan completed a degree in agricultural science at CSU before studying the effects of reproduction on staple strength in a PhD at UNSW.  She spent 5.5 years at Walpeup, Victoria, as senior livestock officer investigating sheep production systems.  She commenced at CSU in 2006 as part of  the EverGraze project which is evaluating means of increasing reproduction, production and profit from sheep systems using perennial plants.

Current research is focussed on nutritional management of ewes to maximise lamb numbers, and simulation modelling of sheep production systems.  Previous research at CSU has been in the areas of management to improve lamb survival, increasing ovulation rates, and optimising sheep production systems.
