Harriet is a current PhD researcher that works in partnership with the University of Queensland and the University of Exeter.  She works under the supervision of Professor Rod Wilson (UK), Professor Craig Franklin (AUS) and Professor Al Harborne (USA). In 2017 she graduated from the University of Queensland with Class 1 Honours, during which she investigated culvert design and its implications for the passage of small bodied Australian fishes. Following the successful completion of her honours she worked as a research assistant for the Franklin – Eco Lab. In January 2018 she began her PhD at the University of Exeter after being awarded a QUEX PhD scholarship. Her PhD uses an understanding of integrative physiology to improve sustainable aquaculture practices and gain insights into optimal foraging theory in wild fish.

Research interests  

Harriet’s current research centres on the issue of food security. It is known that global food production will need to increase by 70 % if we are to meet the demands of our human population by 2050. With fish now accounting for up to 17 % of the world’s intake of animal protein, improving the efficiency and sustainability of aquaculture will be key to address this issue. Knowing this, Harriet’s research uses integrative physiology to optimise diets for sustainable aquaculture. She works in collaboration with industry partners on commercially important fish species such as Rainbow Trout in the UK and Barramundi here in Australia. Specifically, she investigates the physiological consequences associated with the digestion of buffering feed additives in fish. The digestion of these minerals could enhance the cumulative costs associated with digestion and lead to a reduction in fish growth efficiency. However, by understanding the impact of buffering minerals on the physiological costs associated with digestion, we can determine an optimal diet that minimises blood chemistry disturbances and the energetic costs of digestion to maximise fish growth efficiency and improve the sustainability of global aquaculture.
