Assistant Professor Uri Lesmes

Research Interests:

Novel food bioactives and formulations, gastrointestinal digestion and microbiome, food-omics and food nanosciences, process-structure-functionality relationships

Short Synopsis:

• Food Chemistry and Biochemistry: Fabrication and characterization of novel food-grade ingredients and formulations. Physicochemical basis of digestion. Metabolomic and proteomic analyses of foods, Prebiotics and antioxidants and their role in foods. Personalization of foods.
 Food technology: Novel strategies to rationally design food colloids and interfaces. Development of structured emulsions and other oral controlled release formulations.
• Emerging food Science and technology: In-Vitro models of the gastrointestinal tract, structure-function relationships, nutritional programming of the gut microbiome. Impact of processing and formulation on food safety and digestive fate.

 

Current international collaborations: Institute of Food Research (Norwich, UK), National Institute of Agricultural Research (INRA, Rennes, France).
