From the site:
The goal of doctoral education in Digital Arts and Experimental Media is to create opportunities for artists to discover and document new knowledge and expertise at the most advanced levels higher education can offer. While creating new art is at the center of all activities in the program, the DXARTS PhD is a research-oriented degree requiring a substantial commitment to graduate-level study and reflection. The Ph.D. degree prepares artists to pursue original creative and technical research in Digital Arts and Experimental Media and pioneer lasting innovations on which future artists and scholars can build.
