Throughout a singular career, built as a teacher in basic education, professor at the university and high level researcher, Senna always defeated the myth of not being possible to coexist the school teacher, the academic professor and the researcher.
Spite of his collection of about 260 published papers, among books, papers and lectures, as well as almost 100 supervisions of PHd, Ms. and Graduate monographs, Senna keeps an intense routine of investigations, constantly renewed in research cycles whose series can be accessed at the site of research group Language, Cognition and Educational Processes. Averse to random researches, his cycles of studies reflect the same focal object: theoretic basis for the teacher as an agent of literacy and reading at Brazilian public schools. Some moments more focused on linguistic issues, another more on knowledge representation, his contribution to the area of literacy and reading takes as primary objects the real subjects of Brazilian society and the circumstances that, frequently, determine their exclusion or school failure.
Current objects of investigation involve mostly the grammatical properties of linguistic systems – such as natural languages, written systems and sign languages as LIBRAS – observed in in-use contexts featuring occurrences of linguistic interferences and metaphoric systems. In the primary interest of Education, Senna seeks to evaluate the impact of social identity over literacy and written skills, under the phenomenon of “in contact cultures”, attested by the recurrent presence of perennial interferences in the use of written language by Brazilian Portuguese speakers and by Brazilian deep deaf competent users of LIBRAS.
