The Interdisciplinary PhD Program in Earth Sciences & Environmental Sustainability (ESES) brings together students and faculty with specialties in several disciplines within CEFNS, and with an interest in working teaching in an interdisciplinary context. Many ESES topics address questions that are useful for decisions and solutions related to environmental issues made by governments, business and society.
ESES students produce discipline-specific science and engineering of the highest quality. They strive to integrate different disciplines from the natural sciences, social sciences and engineering to build, connect and communicate knowledge to increase the broader impacts of their research.
ESES students study how planet Earth is changing due to natural phenomena and human activities over multiple time scales, and from the atmosphere to the Earth’s surface to the deep Earth. They observe, explain, understand, and project trends in earth, environmental, and societal systems, and investigate the drivers and processes that shape natural and social worlds and the interactions between them.
ESES students will select one of the following three emphasis areas, based upon their background and the work they will complete toward their dissertation:
Earth and Planetary Systems
This emphasis will prepare you to pursue research and educational opportunities that:
- advance knowledge in the critical areas for society of energy, natural resources and water, and natural hazards,
- continue the cutting edge research currently being done on the Earth and Planets, and
- apply this knowledge in areas that bridge between the geosciences and physics, chemistry, engineering, and biology.
Climate and Environmental Change
The Climate and Landscape Change emphasis is designed to develop research and educational skills that:
- advance new understandings of natural climate variability,
- improve projections of climate change and its impacts on ecosystems and their hydrological and geological underpinnings (i.e. the landscape), and
- apply this knowledge to informing policy decisions about how best to manage natural resources under changing climate and related environmental stresses.
Engineering Sustainable Systems
The goals of this emphasis are to develop research and educational skills that:
- advance engineering analysis and applications relevant to sustainable development,
- improve the efficiency and effectiveness of engineering processes, products, and education, and
- understand and apply their knowledge in the sustainability contexts of economic viability, environmental compatibility and sustainability, societal impacts and policy development and implications.
- The Engineering Sustainable Systems emphasis is designed for the engineer interested in an understanding of the economic, societal and environmental implications of engineering systems. The student will have a strong background in engineering enhanced by understanding future sustainability of our environment, and will be prepared for careers in academia, industry, and governmental organizations.

You may have no more than 6 units of 400-level courses. These 400-level courses cannot have been used to satisfy the requirements for any previous degree program(s). You must get your dissertation committee's approval for any courses taken outside of NAU.
Be aware that some courses may have prerequisites that you must also take. For prerequisite information click on the course or see your advisor.
- 698 (seminar) courses selected by student and committee (4 units)
- EES 799, for the research, writing, and oral defense of an approved dissertation. You can only count 15 units of dissertation credit toward your degree; however, you may end up taking additional units because you must enroll for it each term while you¿re working on your dissertation. (15 units)
- At least 39 units must be 500- and 600-level courses.
- Your dissertation committee must approve all of your courses.
In addition to completing 45 units of coursework, you must demonstrate your independence, research skill, and experience in a discipline within earth sciences and environmental sustainability by choosing a problem and research area in consultation with your dissertation committee and then satisfactorily completing a dissertation.
Your dissertation research meets our standards when it is soundly based in the theoretical context of the subject, proceeds with a sound design that gives due attention to statistical adequacy, and concludes with findings and inferences set forth within an appropriate theoretical context. Your dissertation must demonstrate that you have mastered your field of specialization, carried out independent scholarly work, and contributed significant new knowledge. You must pass an oral defense of your dissertation.
We also require that you demonstrate written and oral communication skills in English at a level that will allow you to effectively communicate your ideas and knowledge to a wide range of audiences. Part of this demonstration involves comprehensive oral exams by the end of your 4th semester designed to establish your competence in a breadth and depth of subjects within your emphasis area and the larger field of earth sciences and environmental sustainability.
