- One of his main work activities is very much connected to teaching: the creation of printed and online materials for teaching Spanish and Italian to Italian and Spanish speakers respectively. An example of this activity are publications for schools, such as Gramática en contraste (2018, Bermejo, Barbero, San Vicente) and for university learners, such as Contrastiva – Grammatica della lingua Spagnola (2012, Barbero, San Vicente, Bermejo) and multimedia courses of Spanish and Italian 9 Aproches (2009) and 9 Passi (2009 and 2011).
- His scientific activity and his research interests are also related with grammar and the teaching of Spanish and Italian as foreign languages, in this case from a historiographic point of view and with a grammaticographic and metalexicographic approach. In fact, he catalogued and studied grammars of Italian for Spanish-speakers published in the 18th and 19th centuries and he studied the main grammatical issues in Italian-Spanish bilingual dictionaries. He presented his research at international conferences held by important universities, and his publications in this field stand out for their number and quality and were reviewed at national and international level.
- Currently, his research activity continues in the field of grammaticography and without losing sight of lexicography, with the study of the Italian-Spanish grammar tradition of the 20th century; his research is also extending to recent times with the analysis of the verbal syntagma in Spanish-Italian grammars from 1997 to 2015.
