Data Science has its foundations in mathematics, statistics, and computer science. The Department of Mathematics, and within it the Center for Approximation and Mathematical Data Analytics (CAMDA), supports a diverse program offering strong training in the mathematical core of Data Science including approximation theory, compressed sensing, learning theory, numerical analysis, optimal recovery, signal/image processing, as well as targeted application areas. Several of its faculty are also affiliates with the Texas A&M Institute of Data Science (TAMIDS). Ongoing research is supported by grants from the National Science Foundation and the Department of Defense.
