The School of Public Policy research centers focus on issues ranging from international and regional commerce to transportation logistics. Each center is headed by a distinguished SPP faculty member, who harnesses the vast resources of the school and millions of dollars in grants to direct a wide range of projects. From training of startup entrepreneurs provided by the Mason Enterprise Center to e-commerce development in more than 30 countries by the International Center for Applied Studies in Information Technology, The School tackles a plethora of real-world challenges. Many doctoral students, and a select few master's students, are given the opportunity to collaborate with faculty and contribute to centers' research by participating in grant-funded projects and presentations at outside colloquia and conferences.
