Careers

What Can I Do with a Doctor of Philosophy in Earth Science and Environmental Sustainability?

Earth and environmental sciences and their engineering and policy applications are at the forefront of critical issues facing society in the coming decades. Climate change, water scarcity, the growing demand on natural resources, and environmental sustainability are all challenges for the Southwest, the United States, and the global community.

In this program, you'll join a new generation of leaders, scientists, and engineers who will be uniquely trained to tackle these pressing problems. The goal of this degree is to foster integrative and transformative research that lies between the traditional science and environmental engineering sub-disciplines. You will take classes in environmental policy, in-depth seminars in research, an individualized group of classes specific to your emphasis, and classes to help you attain your individual career goals.

With further education, one of these paths is possible:
  • Environmental science and policy expert
  • Applied scientist in energy and environmental and engineering consulting industries
  • Professor
  • Applied scientist in governmental agencies and academe


University Requirements

  • To receive a Doctor of Philosophy Degree (Ph.D.) at Northern Arizona University, you must complete a planned group of courses, from one or more disciplines, ranging from at least 60-109 units of graduate-level courses. Most plans require research, a dissertation, and comprehensive exams. All plans have residency requirements regarding time spent on the Flagstaff campus engaged in full-time study.

Student Learning Outcomes

Purpose Statement

The faculty and ESES PhD Program Committee apply a consistent suite of general learning outcomes to be obtained for each student within the ESES PhD Program.  The student will work with his/her advisor and the dissertation committee to create a program of study to achieve the following competencies:

  • Obtain personal experience and expert knowledge in the entire range of activities that generate scientific knowledge, including:
    • Conceptualization of a dissertation project.
    • Research the relevant scientific literature to assess the current state of knowledge in the student’s specialized field.
    • Identify significant scientific questions and design a research project to address those questions.
    • Obtain outside funding through grant-writing activities.
    • Generate original, specialized datasets to test hypotheses and make inferences.
    • Demonstrate critical thinking skills and the broader impact of the knowledge in writing and successfully defending a dissertation in a public forum.
    • Convey the significance of specialized research at scholarly meetings.
  • Broaden knowledge and skills through a professional experience tailored to advance specific career objectives.
  • Acquire expert knowledge about the specific research topic specialization that includes its major theories, controversies, methods of inquiry, theoretical and methodological challenges, quantitative methodology appropriate to the area of the dissertation connections with related disciplines, and future directions.
  • Obtain experience in academic settings encompassing interdisciplinary research by placing the student’s expert understanding of their individual research project into the broader context of the earth sciences and environmental issues and sustainability.
  • Relate the results of the student’s individual project to the important policy and management pathways that will impact natural and human-dominated systems in the future.

Student Learning Outcomes
Specific additional competencies are expected for each of the three focus areas:

Earth and Planetary Systems
  • Continue the cutting edge research currently being done on the Earth and planets.
Climate and Environmental Change
  • Improve knowledge of other drivers of global-scale environmental change.
Engineering Sustainable Systems
  • Advance engineering analysis and applications relevant to sustainable development.

    Individual program admission requirements include:

    • GRE® revised General Test
    • 3 letters of recommendation
    • Writing sample
    • Personal statement or essay
    • Resume or Curriculum Vitae
Doctoral Requirements
  • Take the following 60 units,  with a minimum GPA of 3.0:

    • ENV 555 (3 units)
    • EES 605, EES 606 (2 units)
    • Professional experience: Any experience that significantly broadens knowledge and skills, and advances the student’s career objectives. The requirement can be satisfied through regular course work or through individualized study that expands the student’s skills in an area outside his/her dissertation but in a professional area related to his/her career goals, or research experiences within the context of the dissertation.  See an advisor. (6 units)
    • Select courses specific to an area of emphasis and dissertation topic, with at least 6 units in the area of emphasis chosen with approval of the student's dissertation committee. (30 units):
      • Climate And Environmental Change Emphasis
        • Graduate-level courses with EES, ENV, BIO or FOR prefixes, or other courses that focus on climate or environmental change
      • Earth And Planetary Systems Emphasis
        • Graduate-level courses with GLG prefix, or other courses that focus on earth or planetary systems
      • Engineering Sustainable Systems Emphasis
        • Graduate-level courses with CENE or ME prefixes, or other courses that focus on engineering sustainable systems

    RESEARCH REQUIREMENTS

    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.

    COMPREHENSIVE EXAM

    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.

    RESEARCH COMPETENCY REQUIREMENT
