Research Interests

My research interests lie at the convergence of food physics, chemistry and engineering. The driving force is to improve the quality of human life through the development of novel bio-based materials for enchanced food quality and functionality.

The focus of my research is to understand how the physiochemical functionality of molecules at the nano- and micro- scales can be controlled to improve macroscopic properties of food and its overall healthfulness. To be specific I want to understand the mechanisms of structure formation in emulsions and nanoemulsions and how the interfacial nanostructure might be modified through the interactions between surfactants, crystals and other additives. The knowledge gained from this research will then be used for the development of multifunctional bio-based nano- and micro- structures to deliver active components in food without any loss in functionality during processing and digestion (e.g. prevention of lipid oxidation or protection against adverse environment of GI tract so that functionality can be delievered in the targeted organs).
