About

Dr Dominic Agyei holds a BSc degree in Food Science and Technology, from KNUST, Ghana; and a PhD in Chemical (Bioprocess) Engineering from Monash University, Australia. After his PhD, Dominic was as an Alfred Deakin Postdoctoral Research Fellow at Deakin University, Australia, where he worked on the use of enzymes in the development of peptide-lipid bio-conjugates for food and pharmaceutical applications.

Dominic is passionate about research that transforms biological processes and materials into high value bioactive and nutritional products and ingredients that positively influence food quality, food functionality and human health. He also has an interest in food safety, as well as the nutritional and health impact of indigenous foods in mitigating malnutrition and food insecurity. He is keen on collaborating with individual researchers and industry partners on the development of high value bioactive and nutritional food products and ingredients, as well as in research involving indigenous foods.

University of Otago Research Theme / Centre involvement

Dominic is a member of Otago Global Health Institute (OGHI), a University of Otago Research Centre that “foster partnerships to help solve global health problems”. He is also a member of Microbiome Otago, a University of Otago Research Theme which studies the “microscopic inhabitants of the human body and their impact on health and disease”; and Food Waste Innovation, a University of Otago Research Theme which measures food waste, develops reduction strategies, applies innovative technology, and works to modify producer and consumer behaviour.
