This grant continues three years of funding for the University Center of Exemplary Mentoring (UCEM) at the University of South Florida (USF). UCEMs provide scholarships and support services to STEM Ph.D. students who identify as African American/black, Hispanic/Latinx, or American Indian/Alaska Native and who are U.S. citizens. Supported students, known as Sloan Scholars, receive a $40,000 stipend, a standard doctoral student support package, and are eligible to participate in a host of professional development and mentoring opportunities designed to maximize the chances of succeeding in graduate study. For each supported student, UCEMs provide a full doctoral support package to a second minority student through an institutional matching program. In addition to scholarships, grants funds will support the continuation, expansion, and improvement of a host of recruitment, retention, and student support activities, including production of an operational manual of recruitment and retention processes and activities, further development of USF’s multidimensional mentoring model, and programs to help coordinate activities between Sloan Scholars in USF’s Engineering School with those in its College of Marine Sciences.
