The National Institutes of Health’s (NIH) Big Data to Knowledge (BD2K) Training Coordinating Center (TCC) exists to equip current and future generations of biomedical researchers with tools to navigate the rapidly evolving and increasingly complex ecosystem of data science. As ever larger quantities of data are obtained and generated by diverse domains ranging from genomics to health informatics to environmental research, powerful new methods have emerged for confronting critical research questions through the exploration, preparation, analysis, visualization and interpretation of Big Data.
