Natural Resources Ph.D.

All students must meet the Requirements for the Doctor of Philosophy Degree


The Ph.D. program provides the opportunity for focused, in-depth research in any of the specialties of the school, while fostering an interdisciplinary appreciation and perspective through course work and interactions with ecological, physical, and social scientists in an integrated academic setting. Students can develop programs in areas such as pollution ecology, recreation and tourism, conservation biology, and environmental policy, as well as any of the traditional natural resource disciplines featured in the master's program. In addition, formal course work and practical experience in college-level teaching are an important component of the doctoral curriculum.
