Dr Fairweather's research over her career has included a diverse collection of projects encompassing agriculture, hydrology, irrigation and climate research in a number of Universities including the University of Lethbridge in Canada, UNE and USC as well as Government agencies in NSW, QLD, Canada and the United Kingdom and Cooperative Research Centres (Beef and Cattle Industry and Irrigation Futures).
Dr Fairweather's PhD centred on the modelling of nutrients and effluent from a Feedlot and was followed by a Post Doctoral Fellowship through a Canadian Science and Engineering Research Council award.
On her return to Australia, Dr Fairweather worked for the NSW Government, where she delivered on a range of climate and agricultural projects for various funding agencies (the Grains Research and Development Corporation, Land and Water Australia) and a State Government research grant to develop a climate change adaptation tool in a GIS framework.
For several years Dr Fairweather was privileged to lead the Toolkits Program, which was one of the two major irrigation research programs conducted by the CRC for Irrigation Futures, involving collaboration with a range of Universities and Government agencies across Australia.
Before joining USC, Dr Fairweather led the development of the science component of a project to revise the flood risk assessment methodology to take account of climate change in the relevant Qld State Planning Policy.
