Research Interest

My research interest is mainly focused on the use of multi-disciplinary approaches in food quality and safety management to mitigate foodborne pathogens and understand the dynamics of food handling practices, food fraud, and waste in the food chain. In these pursuits, I develop diagnostic tools, based on international and national standards, to unravel the dynamics of the socio-technical system and how they affect food safety and food integrity of specific foods.
