The primary advisor is typically a regular or affiliated faculty member of the University of Delaware (most Winterthur Museum faculty are also affiliated UD faculty). When a student’s thesis requires technical, material, and/or artistic support, a secondary advisor (including someone who might work for another University) with such expertise may also support the student. This expert may serve in an informal capacity, offering guidance to students as needs arise, or they may serve in an official capacity, as co- or secondary approver, in which case they must hold a graduate degree equal to or higher than the program’s M.A. degree.
