It is now almost four decades since Gaye started teaching at university, teaching across a number of different courses including agribusiness, agricultural science, animal science, aquaculture, equine science, food science and veterinary science. The common denominator for all of these courses is the field of animal (including aquaculture) nutrition, ranging from feeding the animals through to the impacts on (animal) product quality. Other subjects taught have included biochemistry, dairy production, intensive and extensive beef production, pasture management, pastoral (animal) production systems and toxicology.

The major focus of research has and continues to be evaluation of non-traditional feed resources, including agro-industrial byproducts (e.g., citrus pulp, grape seed meal, banana leaves), invasive weeds (e.g., giant mimosa, water weeds such as azolla) and potential new feeds (e.g., cultivated rangeland plants.

This research has involved many different animal species including dairy goats, meat goats, sheep, beef cattle, pigs and horses.  Many other research areas have been explored as a consequence of supervising a large number of Honours and HRD students. Current research centres on evaluation of industrial hemp biomass and seed byproducts for inclusion in livestock rations (ruminants) or as potential nutraceuticals (horses and companion animals).
