Jose Antonio Langarita’s professional interests have centred, since the beginning of his career, on the study of sexual and gender diversity from an interdisciplinary perspective. In the course of his research, he has made use of knowledge and methodologies from different fields of social sciences. This has led him to publish the results of his work in scientific journals on anthropology, geography, social work and other transdisciplinary journals, as well as books and book chapters in several languages. Dr. Langarita has been the international coordinator of the Diversity and Childhood project (2019-2021) and the Colourful Childhoods project (2022-2024), both funded by the European Commission and focusing on sexual and gender diversity in childhood.
