CIBERDEM, the Spanish Biomedical Research Centre in Diabetes and Associated Metabolic Disorders, launches its international mobility fellowship programme for experienced researchers: DIATRAIN.The DIAbetes Trans-national Research Advancement for INvestigators (DIATRAIN) is a new institutional mobility framework within CIBERDEM which aims to provide experienced researchers, including both CIBERDEM staff members and researchers working at foreign institutions, with unique career development opportunities. This will foster international research collaborations in the field of diabetes and associated metabolic diseases.Bringing together basic scientists and clinicians, CIBERDEM is a Spanish research consortium that seeks to promote quality research and to foster the transfer of knowledge and technology from research to healthcare practices. This translational research would be impossible on the local level but CIBERDEM provides an invaluable infrastructure in its researchers that makes such an approach possible on the national one. CIBERDEM is constituted by 32 Spanish research groups located at hospitals, universities and research institutes all over Spain.DIATRAIN is structured into two programmes:COMP-CIBERDEM Outgoing Mobility Programme (4 calls, with 3 awardees per call): CIBERDEM postdoctoral staff with a permanent position are eligible researchers; the fellowship duration is from 6 months to 1 year; the destination is any non-Spanish research organisation (EU and Third countries).CIMP-CIBERDEM Incoming Mobility Programme (2 calls, with 2 awardees): Any experienced researcher with a doctoral degree and working at a foreign research organisation for more than 24 months is an eligible researcher; 2 years is the fellowship duration; any CIBERDEM research group is the destination.DIATRAIN will offer the resources that fellows need to have a successful research experience abroad that will later serve as a tool for personal and professional enrichment.
