DIMACS (the Center for Discrete Mathematics and Theoretical Computer Science) facilitates research, education, and outreach in discrete mathematics, computer science theory, algorithms, mathematical and statistical methods, and their applications. Our multi-year special focus programs address research themes that require topical expertise in these areas, have potential for societal impact, and are poised for advance. Our educational programs include materials development for high school and college classrooms, an extensive summer undergraduate research program, and teacher training programs.
