Higher Degree by Research Candidate
School of Agriculture, Food and Wine
Faculty of Sciences, Engineering and Technology
David is a Ph.D. candidate in the School of Agriculture, Food, and Wine. His Ph.D. research investigates the use of eco-friendly processing technologies to improve the food production system through the sustainable valorization of underutilized resources. He aims to implement a circular economy model in the food value chain in line with sustainable development goals (SDGs) by replacing the conventional use of toxic solvents in the biorefining of biomass with alternative environmentally friendly solvents. His ultimate goal is to re-use the so-called waste and byproducts from the food processing sector and create highly valued bioproducts and biomaterials with potential applications in the food, nutraceutical, cosmetic, pharmaceutical, and packaging industries.
