    • Describe your leadership, work experience, service experience, or other significant involvement with racial, ethnic, socio-economic, or educational communities that have traditionally been underrepresented in higher education, and how these experiences would promote a diversity of views, experiences, and ideas in the pursuit of research, scholarship, and creative excellence
