Associate Professor Katheline Hua is an expert in aquaculture nutrition. She has extensive research experience in working with both warmwater and coldwater fish species.

Associate Professor Hua holds a PhD in Fish Nutrition from the University of Guelph, Canada. She worked at the University of Guelph as a Postdoc fellow and adjunct professor. Afterwards she worked as a Junior Professor at the Humboldt University of Berlin, Germany before joining JCU. Her primary research interests are nutrient requirement and utilization of fish, optimal feed formulation, alternative sources to replace fish meal and fish oil, functional ingredients and feed additives. One of her expertise areas is nutritional modelling, exploring the synergy of empirical and modelling approaches to integrate and synthesize information related to optimal aquaculture feeds.

Associate Professor Hua has a solid track record of securing research funding to carry out basic and applied research. During her junior professorship at the Humboldt University of Berlin she was awarded research grants from two prestigious granting agencies in Germany: German Research Foundation and the Federal Ministry of Education and Research.

With her strong research interest in fostering sustainable aquaculture feeds to solve real world problems, Associate Professor Hua has also been leading a number of industry co-funded projects. She has been collaborating with several key players in global aquaculture feeds industry, which include top aquaculture feed producers, multinational feed additives and agri-food companies.

Associate Professor Hua is the lead PI of the red snapper nutrition project ($1.36 million) and a Co-PI of the feed supplement project ($1.33 million) under the Singapore Food Story (SFS) R&D Programme.
