• Must complete the TOEFL Exam with scores sent to the College of Graduate Studies (international students only).
• Must submit a statement of research interests and career goals as pertains to pursuing a PhD in Environmental Science. 
• Must submit three letters of recommendation from individuals familiar with the applicant’s academic or professional experience.
• Typically, will have a minimum 2.8 cumulative grade point average (on a 4.0 scale) for all undergraduate and graduate (if applicable) coursework.

Follow these steps to complete the Georgia Southern application:

Georgia Southern University is accredited by the Southern Association of Colleges and Schools Commission on Colleges (SACSCOC) to award associates, baccalaureate, masters, educational specialists and doctorate degrees.

This course will explore the complex interdisciplinary nature of environmental science. Students will investigate how interdisciplinary approaches incorporating the scientific disciplines, mathematics, policy, and management can be combined to address real-world environmental issues. The course will often be team taught by 3 faculty and will contain a mix of lecture and project based learning. All students will gain scientific writing experience by developing a research proposal.

This course covers major principles of evolution and ecology, and application of these principles to the management of species and ecosystems. Topics include the origin and maintenance of genetic variation, evolutionary change of populations over time, the role of speciation and extinction in regulating biodiversity, and ecological interactions between organisms and their abiotic and biotic environments, at the scales of individuals, populations, communities, and ecosystems. These principles will be applied to conservation issues arising from global environmental change, and addressing these issues through sustainable management of species and ecosystems.

This course examines biogeochemical cycles (C, N, P, S, and metals), the environments in which these processes occur (hydrosphere, lithosphere, atmosphere, and biosphere), the chemical reactions that take place during these cycles, and the microorganisms that influence them. Additionally, a major theme is the effect of human activities on biogeochemical cycles.

This course provides an overview of statistical analyses and methods used in studies related to the biological and environmental sciences. The general emphasis of this course includes organizing and summarizing data, drawing inferences from population samples via estimation and significance tests, linear and generalized regression, random-effects models, time-series, and spatio-temporal analysis.

This course is designed to introduce methods of geospatial data acquisition, processing, mapping and analysis (from the field and from online geodatabases) in the environmental sciences.

An introduction to the application of mathematics to various biologically and environmentally related problems, which can be analyzed both analytically and numerically. Computational approaches for model analysis are introduced and include numerical solutions of linear and nonlinear models, numerical differentiation and integration, data fitting, and other numerical methods.

This course covers a variety of chemical fields as they apply to the five essential human needs: water, food, health, waste management, and energy. Various materials, including metals, inorganic and organic compounds, polymers, and proteins, as well as their applications, will be introduced. Basic research and cutting-edge technologies will be discussed.

An introduction to the study of environmental phenomena that exhibit complexity emergent from a wide variety of parameters. An interdisciplinary course that employs the study of a variety of physical, biological, and chemical problems. Students learn how to construct and analyze minimal mathematical, physical, and computational models that provide informative answers to precise questions about: population dynamics; species interactions (e.g., competition, predation, parasitism); reaction kinetics; sedimentation; biological oscillators; coupled reaction networks; molecular motors; limit cycles; reaction diffusion; nitrogen fluxes in low-relief watersheds; recovery from acid deposition in mountain streams; bacterial patterns; nitrogen budgets on permaculture farms; and the sustainability of human activity on the Earth.

Do I need to secure a potential faculty advisor before I submit an application to the program?

• Yes. Students will only be admitted to the Environmental Science Ph.D. program if a faculty member has agreed to serve as their Ph.D. advisor. Thus, applicants should identify and communicate with potential advisors prior to the application process. Information on faculty within the College of Science and Mathematics can be found on the various departmental pages. See https://www.georgiasouthern.edu/cosm/departments/

Can I use an unofficial transcript for application purposes?

• Official transcripts are required for admission into the Environmental Science Ph.D. program. International applicants must have their official transcripts evaluated by a NACES accredited evaluation service. See this page for more details: https://cogs.georgiasouthern.edu/admission/applynow/

Is there a possibility of getting the GRE exam requirements waived?

• There is no GRE waiver available for the Environmental Science Ph.D. program.

Is the Duolingo English test accepted in place of the TOEFL?

• No, international applicants must complete the TOEFL exam. See this page for more details:  https://cogs.georgiasouthern.edu/admission/applynow/

Is there a possibility of getting my application fee waived?

• We are unable to waive the application fee for the Environmental Science Ph.D. program.

Are there funding opportunities for students pursuing the PhD in Environmental Science?There are a limited number of teaching assistantships available to graduate students pursuing the PhD in Environmental Science, but these are not guaranteed upon acceptance and are very competitive. Alternative sources of student support are sometimes available through external funding (e.g., grants and contracts) that have been obtained by faculty. As noted above, potential graduate students must secure a faculty advisor to be admitted to the PhD program so discussions regarding the sources and availability of student support should be completed and negotiated between the student and faculty advisor. In addition, a limited number of out-of-country tuition waivers are available to international students through the Office of Graduate Admissions (see: https://cogs.georgiasouthern.edu/admission/applynow/).

The Graduate Student Organization (GSO) is committed to representing and supporting the interests of all current and prospective graduate students at Georgia Southern University and seeks to support scholarly activities as well as promote social opportunities for the development of graduate students.
