Born in the outskirts of Rio de Janeiro, Lucas grew up in an evangelical family of workers who encouraged him to pursue an educational path to achieve a better future and to overcome the harsh reality that his family faced. Lucas persisted in his dream and was admitted into Colégio Pedro II, a traditional public school known for offering quality education in the city of Rio de Janeiro. There, he enjoyed an education and a network of opportunities different from that experienced by most young people in Rio de Janeiro, which is why, during his adolescence, he became interested in systemic changes to provide more opportunities for them.

His education led him to engage in collective action in social impact and influenced his decision to enroll in the History course at the Federal University of Rio de Janeiro (UFRJ), to become a teacher and transform the trajectory of young people through education. His work began in grassroots organizations of the student movement, and throughout, he became an ambassador for Construindo o Futuro, an organization of adolescents for sustainable development.

He is a co-founder of Construindo o Amanhã, a platform that encourages debate and the development of public education policies from the perspective of youth, and is also a teacher in community education courses and private schools. Today, he is a part of the Aspen Institute Forum for Community Solutions (FCS) Global Opportunity Youth Network (GOYN)  Advisory Group for Decola Cria in Rio de Janeiro. He is working with other young people from different backgrounds on inclusion and identities, who are working collectively to make necessary changes.
