Glendale; the Downtown Phoenix campus; and the Polytechnic campus in Mesa. ASU also offers courses and degrees through ASU Online and at the ASU Colleges at Lake Havasu City in western Arizona, and offers regional learning programs in Thatcher, Yuma and Tucson. The Arizona Board of Regents appoints and elects the president of the university, who is considered the institution's chief executive officer and the chief budget officer. The president executes measures enacted by the Board of Regents, controls the university's property, and acts as the university's official representative to the Board of Regents. The chief executive officer is assisted through the administration of the institution by the provost, vice presidents, deans, faculty, directors, department chairs, and other officers. The president also selects and appoints administrative officers and general counsels. The 16th ASU president is Michael M. Crow, who has served since July 1, 2002. Campuses and locations Academic programs are spread across four distinct campuses in the Phoenix Metropolitan Area; unlike most multi-campus institutions, however, ASU describes itself as "one university in many places", inferring there is "not a system with separate campuses, and not one main campus with branch campuses." The university considers each campus "distinctive" and academically focused on certain aspects of the overall university mission. The Tempe campus is the university's research and graduate school center. Undergraduate studies on the Tempe campus are research-based programs that prepare students for graduate school, professional school, or employment. The Polytechnic campus is designed with an emphasis on professional and technological programs for direct workforce preparation. The Polytechnic campus is the site of many of the university's simulators and laboratories dedicated for project-based learning. The West campus is focused on interdisciplinary degrees and the liberal arts, while maintaining professional programs with a direct impact on the community and society. The Downtown Phoenix campus focuses on direct urban and public programs such as nursing, public policy, criminal justice, mass communication, and journalism. ASU recently relocated some nursing and health related programs to its new ASU-Mayo Medical School campus. Inter-campus shuttles and light rail allow students and faculty to easily travel between the campuses. In addition to the physical campuses, ASU's "virtual campus" at the university's SkySong Innovation Center, provides online and extended education. The Arizona Board of Regents reports the ASU facilities inventory totals more than 23 million gross square feet. Tempe campus ASU's Tempe campus is in downtown Tempe, Arizona,
