Welcome to the Department of Social and Decision Sciences

The Department of Social and Decision Sciences (SDS) is an interdisciplinary department that offers undergraduate and graduate programs that combine studies in the social sciences with the practical skills needed to excel in key decision making roles in the public and private sectors.

Students learn how to combine intellectual ideals with the realities of human and organizational behavior and to apply these lessons across a wide variety of endeavors, ranging from government service to leadership positions in the information economy.


The mission of the Department of Social and Decision Sciences is to provide intellectual leadership in the social sciences, brought about by the power of a transdisciplinary environment for research and learning, for teaching and training, and for solving social problems.
