In his research, directed by Professor Mauricio Alejandro Matus López and summarized in several scientific articles, the Costa Rican graduate in Political Science analyzed the need to develop a national system of support and care for dependency for his country, making a comparative calculation with the regional prevalence and other models in the world, while carrying out a diagnosis of the phase prior to the decree that was finally sanctioned by that country. In 2021, Costa Rica became the second country in the region to implement a National Long-term Care System, after Uruguay. 

In his conclusions, Chaverri explains how Costa Rica's efforts in this area will be fundamental in determining the decisions of other middle-income countries when designing their own systems. Likewise, among the lines of research opened up by this work is the study of dependency care policies in Latin America, "an area that has been little explored in the scientific literature", according to Chaverri. The defence panel was made up of professors Camilo Cid Pedraza, Agustín Huete García and MEP Lina Galvez Muñoz.

In 2019, Alexander Chaverri was one of the first beneficiaries of this OEI scholarship programme that seeks to strengthen the training of new PhDs in Ibero-America. The programme provides financial support to students and university professors who decide to carry out their doctoral thesis at a university in an Ibero-American country other than the one where they have completed their previous studies or where they are teaching.

Paulo Freire (Brasil, 1921-1997) was one of the greatest and most significant educationalists of the 20th century. The considered ‘pedagogue of the oppressed’ taught a new way for the relationship between teachers and students with his principle of dialogue. His ideas influenced democratic processes all over the world and remain valid today.
