This is a project funded by the Spanish Ministry of Economy and Competitiveness and the European Social Fund aiming to answer these questions. We investigate what genres academics use to communicate in their everyday professional practices. We also investigate how, in using academic genres, they may use several academic languages. We seek to understand how ecologies of genres and ecologies of languages are shaped in today’s academic settings in the context of ongoing internationalization processes at universities. How internationalization policies and language policies at universities make these ecologies evolve over time is one of our main investigative goals.
