The University of Barcelona's Bioethics Commission (CBUB) evaluates research projects to be carried out by members of the University of Barcelona community (academics and researchers) that are presented in competitive calls managed through the University's Office of Research Management (OGR) and Office for International Research Projects (OPIR). The favourable opinion of an ethics committee at a research centre where a research project is going to be carried out is a legally established requisite for initiating any research involving humans, biological samples of human origin or personal data.
