The overall aim of this joint exchange programme (GEoCoDE: Genomic and Epigenomic Complex Disease Epidemiology) is to establish a multilateral network of researchers active in genetic and epigenetic epidemiology, strengthen research capacity through exchange of knowledge and expertise in both areas and develop integrated approaches to investigate both genetic and epigenetic aspects of complex disease. The joint exchange programme will involve 28 partners and will be realised through a series of short and long term periods of staff exchanges between European and Third Countries and annual workshops at which all participating partners will be represented. The programme will be co-ordinated by University of Bristol (UK). The programme will be concerned with genetic and epigenetic epidemiology and work undertaken will be of direct relevance to a wide variety of complex diseases including cancer, type 2 diabetes, obesity, cardiovascular disease and perinatal health problems. The overall aim of the proposed exchange programme is to stimulate synergy and support internationally recognised research in this rapidly evolving field in the ERA and in participating Third Countries. A focus on translational aspects of genetic and epigenetic epidemiology will be actively maintained.
