The Ph.D. program in this department is considered one of the foremost in the country. The doctoral degree is offered in a wide range of fields from Ancient Near Eastern art and archaeology to contemporary art and critical theory, with most of the major fields in between strongly represented: Aegean, Greek, Roman; western Medieval and Byzantine. Archaeology at Columbia encompasses a range of disciplines, cultures, and approaches. In the Department of Art History and Archaeology, students and faculty come together under the joint title of the department through studies of urbanism, architectural space, and the context of visual images. Archaeology students here have access not only to the rich opportunities the department has to offer, but also to the Program in Archaeology that is a cooperation of six departments at Columbia University, as well as the network of archaeologists, archaeological sites, and museum collections in New York City as a whole.
