Since my early childhood I showed a great interest in languages​, in communicating with others, and I developed a particular skill that allowed me learning languages ​​without great difficulty. I took a chance on those circumstances and I devote myself in the nineties to the knowledge of foreign languages ​​such as French, English, Italian, German or Portuguese.

In 2008 I completed Engineering studies, always combined with my passion for languages. In 2009, when I discover my educational vocation, I was forced to learn Valencian, a lingual variation of Catalonian language, that has helped me up today in Barcelona, the place where I live, and it is a worthy tool for my work , related to the treatment to the people. Special emphasis to the acquisition of technical English and German during my university studies.

Such a educational vocation has allowed me to gain vast academic knowledge, useful learning tools and a cultivated teaching methodology endorsed by a long list of qualifications. On the technical and scientific fields highlight my passion for the sciences that study the universe: astronomy, astrophysics, cosmology, etc, Also my love and respect for the Nature, the Environment and our Mother Earth make me interested in archeology and paleontology, prehistory, natural sciences and other geosciences.
