Environmental Sciences Ph.D. Program


The mission of the Doctor of Philosophy program in Environmental Sciences is to meet local, state and national needs for outstanding, interdisciplinary-trained graduates who will assume positions of responsibility in industry, government, and non-government organizations. The Environmental Sciences Ph.D. program is designed to develop environmental scientists who can function as researchers or high-level managers. This degree is awarded for demonstrated scholarly excellence in study and research that provides a significant contribution to the complex field of the environmental sciences.

This program is unique in focus, building on a core group of program faculty with recognized expertise in the departments of Biology, Chemistry, Geological Sciences, Physics, Pharmacology/Toxicology and Mathematics and Statistics. This interdisciplinary Ph.D. program consists of three areas of excellence: 1) Environmental Biology: Genes, Organisms and Ecosystems, 2) Environmental Earth Sciences and 3) Environment and Society. These areas of excellence will provide students with high-demand environmental skills that are interdisciplinary-based yet well grounded in more traditional areas of environmental biology, chemistry, toxicology, geophysics and hydrogeology.

This program leads to the Doctor of Philosophy degree in environmental sciences. This program is unique in its focus, building on a core group of program faculty with recognized expertise. The interdisciplinary Ph.D. program consists of three areas of excellence: 1) Environmental Chemistry and Toxicology; 2) Environmental Stressors; and 3) Environmental Geophysics Hydrogeology. These areas of excellence will provide students with high-demand environmental skills that are interdisciplinary-based yet well grounded in more traditional areas of environmental biology, chemistry, toxicology, geophysics and hydrogeology.


Entrance Requirements

A student will be admitted to the Environmental Sciences Ph.D. program with a baccalaureate degree or a master’s degree from a supporting discipline (e.g., biology, chemistry, geology, or physics); satisfaction of the admission requirements as set forth by the School of Graduate Studies; and a record that indicates potential for a career in environmental sciences, as evaluated by the program’s Admissions Committee (consisting of program faculty from participating departments). Students should enter the program with knowledge of one of the supporting sciences and having successfully completed biology, inorganic and organic chemistry, physics, statistics, and calculus. If a student is deficient in one of these areas, the Admissions Committee may recommend the undergraduate courses that should be completed during the first year. Determining deficiencies will be dependent on the student’s area of focus.

Admitted students will be expected to demonstrate strong academic ability. Submission of Graduate Record Examination (GRE) scores is required. International students must have a TOEFL score of at least 600/250.

Degree Requirements

Students are asked to master a series of core courses, advanced content courses, seminars, and laboratory rotations (see Curriculum below). These serve as an interdisciplinary base for the development of dissertation research. The institution awards the degree when the student satisfactorily completes the required work.

Waiver of Program Requirements

Students may petition to be exempted from all or part of the core curriculum, usually by scoring a passing grade on an appropriate proficiency examination. Students with a master’s degree in a relevant field of study will be exempted from appropriate course requirements and 45 credit hours. Students may also petition for waiver of credit for previous graduate courses taken in another accredited program. Advanced course credit of up to 12 credit hours may be waived providing (a) the grade attained in each course is a B or better, (b) the course was taken within four years of the actual waiver, and (c) the course relates to the area of concentration chosen in this program. Petitions for obtaining credit for laboratory experiences may be made, subject to the same credit hour limitations and time constraints as for courses.

Petitions for exemption or waiver should be submitted to the program director, who will make the final decision, and who may, if necessary, seek a recommendation from the Curriculum Committee.

Each student chooses a faculty member to guide and direct the dissertation research on a daily basis. In addition, a supervisory committee is formed to periodically review the student’s progress. The relationship between the student, the faculty advisor, and the committee is central to the program. The committee determines when the research may be considered complete and must approve the written dissertation, as well as the student’s public defense of it. The committee certifies to the program director the competency and achievement of the dissertation.


The program is a cooperative effort among departments within the College of Science and Mathematics and the Department of Computer Science and Engineering in the College of Engineering and Computer Science. Program faculty at Wright State reside in the departments of Biochemistry and Molecular Biology, Biological Sciences, Chemistry, Computer Science and Engineering, Geological Sciences, Mathematics and Statistics, Pharmacology and Toxicology, and Physics.

Financial Assistance

Graduate assistantship and fellowship support is available to students on a competitive basis. Students awarded support are eligible for stipends and remission of tuition fees the first two years. The Fellowship is for $18,707 (plus tuition remission) on a 12 month basis. The first year is a Research Assistantship (12 months), the second a Teaching Assistantship (12 months), and then your major professor supports you with their research funds for the remaining time of your Ph.D.

Also available is the new YSI Environmental Sciences Ph.D. Fellowship. The Research Fellowship is for a minimum of $20,000 plus tuition and fee waivers. This prestigious award will be given to a qualified applicant accepted into the Environmental Sciences Ph.D. program at WSU. Students may apply with either a B.S. or M.S. degree from a relevant major (e.g., biology, chemistry, geology, physics, toxicology, environmental health sciences). The program provides a strong interdisciplinary focus both in the course work and dissertation research, with a focus on contaminant fate and effects in three areas of faculty expertise: environmental toxicology and chemistry, environmental stressors, and environmental geophysics and hydrogeology. Review of applications for the 2006-2007 Academic Year will begin in January 2006 and continue until the position is filled.

Students with financial assistantships must register as a full-time student each quarter (at least 12 credit hours of relevant graduate courses).
