Short CV

Research Interests

Her scientific activity is focused on the food microbiology, with particular attention to microbial communities and their evolution during the production and the ripening of different fermented foods.

She identified and characterized, by phenotypic and genetic techniques, a large number of microorganisms isolated from typical fermented foods and she studied the interactions between microorganisms of food interest.

Another important topic is addressed to the study of potentially probiotic bacteria, by the characterization of their resistance to gastrointestinal and food-processing stresses, and of their health activities.

Other activities concern the study of novel tools for the improvement of the shelf-life of fresh foods.

She is Scientific Responsible for the Institute of Food Science of two Projects PSR 2007-2013 Campania Region, namely DERFRAM (Sviluppo di derivati di frutta ad elevato grado di sicurezza d’uso) and QUINOAFELIX (Introduzione della quinoa in Campania per la produzione di alimenti a valenza funzionale ed elevato valore nutrizionale), dealing with the improvement of traditional fruit juice and the production of functional food based Quinoa Chenopodium quinoa willd, respectively.

She was also involved in several Regional, National and European research projects. In particular, in the years 2008-2010, she took part to the activities of the Sixth Framework Programme entitled “NOvel Vegetal-based Extracts Additives for CHEMical-Free FOOD (NOCHEMFOOD) – Contract n. FOOD-CT-2006-023060”.

She is author of many publications about the microbiology and the biotechnology of different food.
