The University of Denver's PhD in geography includes areas of emphasis in biogeography, climatology, cultural geography, economic geography, environmental change, geographic information science, geomorphology, human environment interaction, Latin America, population, Quaternary studies, transportation geography, water resources and urban geography. The PhD is the highest achievable degree in the field, and students in the program will be expected to produce a high-quality dissertation of substantial scope. Students who achieve the PhD can pursue careers in higher education, with federal and state agencies, and in a range of other fields requiring specialized geographic knowledge.

The department's modestly sized graduate population leads to many advantages: small classes, personal attention, and the chance to develop rewarding relationships with faculty, staff and other students. The department also features excellent facilities and resources, with updated offices, labs and classroom spaces. It also offers numerous opportunities for field training through a range of trips and field courses, both in the U.S. and abroad.
