Aldo Parra is an assistant professor at Universidad del Cauca, Colombia. He conducts research on ethnomathematics and mathematics teacher education in contexts of cultural and linguistic diversity. This work demands the use of ethnographic methods and cultural theories to investigate issues like cultural identity, subjectivity, and development. The quest for research methods more communitarian, participative and grass-rooted is characteristic of his work. Aligned to that, he is interested in decolonial studies and alternative philosophies for mathematics. Aldo is trying to develop theoretical concepts for a non-instrumental teacher education in mathematics with preservice and in-service mathematics teacher education. Currently, he is the editor-in-chief of the Latin American Journal of Ethnomathematics.
