The mission of the MRC Centre for Global Infectious Disease Analysis (MRC GIDA) is to be an international resource and centre of excellence for research and capacity building on the epidemiological analysis and modelling of infectious diseases, and to undertake applied collaborative work with national and international agencies to support policy planning and response operations against infectious disease threats. We undertake a wide range of innovative world-class research that can make a demonstrable economic and social impact; carrying out research on emerging and endemic disease, with a focus on ensuring modelling is translated into practical policy guidance for planning and responding to infectious disease threats. As such, over the last decade we have invested heavily in building close collaborative partnerships with public and global health agencies (notably the World Health Organization (WHO), where we are a Collaborating Centre for Infectious Disease Modelling), governments and non-governmental bodies across the world. As of 1st April 2018 the MRC Centre for Outbreak Analysis and Modelling became MRC GIDA. Reflecting our change in name, we are now increasing in size to have a broader focus, covering a wider range of disease areas, and five cross-cutting themes reflecting our revised structure; Outbreak Analysis and Modelling, Global Health Analytics, Vaccines, Antimicrobial Resistance, and Methods and Tools. With approximately 175 researchers, we are one of the largest centres of infectious disease modelling expertise. This gives us a unique capacity to respond to emerging threats such as Ebola and Zika with real-time analysis and predictive modelling – and to provide timely evidence-based input to urgent policy questions for major endemic diseases such as HIV, malaria and tuberculosis. Much of our work is highly interdisciplinary, spanning statistics, mathematical modelling, epidemiology, genetics, intervention science and health economics.
