What Can I Do with a Doctor of Philosophy in Earth Science and Environmental Sustainability?
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
- Applied scientist in governmental agencies and academe

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.
