Last week, the National Science Foundation (NSF) released a solicitation for a new program, Transdisciplinary Research in Principles of Data Science (TRIPODS). This program aims to bring together the statistics, mathematics, and theoretical computer science communities to develop the theoretical foundations of data science through integrated research and training activities. TRIPODS builds off existing investments at NSF in big data, including the Big Data Regional Innovation Hubs and the Critical Techniques, Technologies and Methodologies for Advancing Foundations and Applications of Big Data Sciences and Engineering (BIGDATA) program, among others. This program also follows the release of NSF’s 10 Big Ideas for Future Investments, and is seen as a critical component to one idea, Harnessing Data for 21st Century Science and Engineering. The submission deadline for required Letters of Intent is January 19, 2017 while the deadline for full proposals is March 15, 2017.
