The mission of the Administrative Core is to support Center activities, including facilitating faculty development, providing programmatic enhancements, creating engagement opportunities, promoting the use of Core resources, and evaluating the Center’s vision to enable long-term sustainability. The Administrative Core organizes and leads our efforts to understand the unique and complex causes and consequences of substance use by supporting and mentoring faculty who use complementary approaches across a variety of disciplines. The Administrative Core is led by our Center Leadership Team and Center Coordinator.
