Doctor of Philosophy (Ph.D.) in Environmental Science

Environmental Science is an academic discipline that incorporates multiple fields of scientific study — such as physics, biology, geology, geography, and chemistry — in order to study the environment and find solutions to environmental problems.

About This Program

The Ph.D. degree program in the School of the Environment is an extension of the Master's degree program that will prepare scientists to address environmental issues through innovative and applied research.

The Doctor of Philosophy (Ph.D.) in Environmental Science requires a minimum of 80 semester hours to complete.

Degree requirements ensure that all Ph.D. candidates develop independent and critical thinking skills, have a broad knowledge-base of environmental science, and have an in-depth knowledge of their specialized area of study. This program utilizes graduate courses offered in other departments in the university that are complimentary to the program, as necessary.

Completion of this degree program requires 80 credit hours of graduate-level course work and research, as well as maintaining a 3.0 cumulative grade point average throughout all coursework.

Concentration offerings include:

  • Environmental Chemistry
  • Environmental Policy & Risk Management
  • Aquatic & Terrestrial Ecology
  • Biomolecular Sciences

Total Credit Hours for Degree: ≤ 80 hrs

*One hour course offered in the fall and spring semesters. All doctoral students, including those who have satisfied the minimum seminar requirements, are expected to participate in the Research Seminar every semester except the semester in which they defend their dissertation.



Applicants for admission should have a Bachelor of Science (B.S.) or a graduate degree in the natural sciences, engineering, mathematics or a closely related area.
The Graduate Record Examination (GRE) combined score of at least 300 in the verbal and quantitative components of the general test and a "B" average in upper level (last 60 hours) B.S. degree course work are required of all applicants.
Students must also submit three letters of recommendation from graduate or undergraduate professors or other persons who can attest to their potential to succeed in the program. Applicants must also meet the general admission requirements of the School of Graduate Studies and Research.
Foreign applicants are required to meet the above requirements in addition to obtaining a score of at least 550 on the Test of English as a Foreign Language (TOEFL).
Admission to the School of the Environment Ph.D. degree program may be subject to space and fiscal limitations.
You will experience state-of-the-art research facilities housed in approximately 6,000 square feet of space in the Humphries Science Research Center. Instruments available to both faculty and students in this facility include ICP/OES, GC/MS, HPLC, AA, and high resolution gamma-ray spectroscopy with fiber optic access to the internet. In addition, the School houses a GIS computer laboratory with high performance computers and high speed internet access. Laboratory equipment is continuously upgraded and replaced to maintain our cutting-edge status. 
The School offers eligible students support through scholarships and work-study assistantships. Students also have opportunities for internships in industry, state, and federal laboratories.
