STATEMENT OF PROGRAM SERVICE ACCOMPLISHMENTS FORM 990, PART III, LINE 4A The Broad Institute operates for educational and scientific purposes to improve human health by using genomics to advance its understanding of the biology and treatment of human disease, and to help lay the groundwork for a new generation of therapies. The Institute defined a new collaborative model for biomedical research, bringing together extraordinary scientists across Harvard, MIT and Harvard-affiliated hospitals and uses new approaches that combine biology, chemistry, mathematics, computation and engineering with medical science and clinical research. Its scientists are committed to understanding the fundamental basis of genome and cell biology, and to developing transformative new approaches to biomedical research. Scientific areas include Chemical Biology and Therapeutics, Genome Regulation, Cellular Circuitry and Epigenomics, Medical and Population Genetics, and Metabolism. Broads researchers bring expertise and collaboration in different technology areas, called Platforms, to collaborate on challenging projects that could not be done within a single research laboratory. Technology areas include Broad Technology Labs, Genetic Perturbation, Genomics, Imaging, Metabolomics and Proteomics. The Institute is focused on using collaborative approaches to make foundational advances in a number of disease areas. These areas include cancer, cardiovascular disease, diabetes, infectious disease, obesity, psychiatric disease, rare disease and immunological disease. The Broad Institute is committed to making the extensive data, methods, and technologies it generates rapidly and readily accessible to the scientific community to drive biomedical progress around the world. OVER 5,800 SCIENTIFIC PUBLICATIONS TO DATE HAVE RESULTED FROM BROAD RESEARCH.
