These lead to experience advocating in Brazil's Supreme Court (STF, the national constitutional court), High Federal Legal Court (STJ), National Council for Justice, National Executive and Legislative branches, and The Inter American System of Human Rights, and National Human Rights Council - CNDH.The Federal or National Public Defender's Office is a constitutional branch of Brazil's State, with the double mission of providing free legal aid to everyone who can't pay for the service in all units of the federal public system of administration and justice, as well as advocating for human rights alongside anyone afflicted by any form of violence, be it state, climate, or economic, and open to any population that faces race, class, gender, migrative, xenophobic, i. e., to any unlawful or undignified biased violence or discrimination. This specific profile of advocacy, from legal aid to the general public, going to institutional and international cooperation guarantees the broad branch of international collaboration established by the institution.Academically, at PUC-RIO, he was a volunteer researcher in the Center for Human Rights and a member of the Research Group on Gender and Democracy. Besides teaching courses in Human Rights and Introduction to Law, he coordinated for two years the Permanent Study Group on the Inter-American System, a period in which the team developed a report on Rio de Janeiro's State incarceration scenario and a manual with means to enforcing human rights in the system.
