Introduction:

The Ph.D. degree program in Environmental Engineering- Air Pollution is a multidisciplinary program that involves the applications of scientific knowledge and engineering solution to control pollution and to provide clean air for the workers in industries. Air pollutants are a complex mix of chemicals emitted by human and natural sources and formed in the atmosphere such as sulfur dioxide, nitrogen oxides, particulate matter, heavy metal trace species, volatile organic compounds, and hydrocarbons. Air pollution engineering consists of two major components, air pollution control, and air quality engineering. Air pollution control focuses on the fundamentals of air pollutant formation in process technologies and the identification of options for mitigating or preventing air pollutant emissions. Globally, air pollution is responsible for over four million premature deaths annually. Air quality engineering deals with large-scale, multi-source control strategies, with focus on the physics and chemistry of pollutant interactions in the atmosphere.

Ph.D. Curriculum

The Ph.D. of Environmental Engineering- Air Pollution requires completion of 36 credits, a set of specialty courses (18 credits) and a Ph.D. thesis (18 credits). The main emphasis of the program is on the successful completion of an original and independent research project written and defended as a dissertation.

Comprehensive Exam

Comprehensive Exam should be taken at most at the end of the 4th semester and is required before a student could defend the Ph.D. proposal. Students will have two chances to pass the Ph.D. Comprehensive Exam. If students receive an evaluation of “unsatisfactory” on their first Comprehensive Exam attempt, the student may retake the qualifier once. A second failure will result in termination from the program. The Comprehensive Exam is designed to ensure that the student starts early in gaining research experience; it also ensures that the student has the potential to conduct doctoral-level research.

Ph.D. Proposal

The Ph.D. proposal must contain Specific Aims, Research Design and Methods, and Proposed Work and Timeline. In addition, the proposal must also contain a bibliography and, as attachments, any publications/supplementary materials. The student must defend their thesis proposal to their committee in an oral exam.

Thesis

A student should choose a thesis advisor (and one or two co-advisors if required) within the first year of being in the Ph.D. program, approved by the Faculty committee. In the second year, a thesis committee suggested by the advisor alongside by the Ph.D. proposal should be handed over for approval. The thesis committee should consist of a minimum of five faculty members. Two members of thesis committee should be from the other Universities at the Associate Professor level. Not later than the end of the 5th semester, a student has to present and defend a written Ph.D. proposal.

Research Progress

A student is expected to meet with his/her thesis committee at least once a year to review the research progress. At the beginning of each university calendar year, each student and the student’s advisor are required to submit an evaluation assessment of the student’s progress, outlining past year accomplishments and plans for the current year. The thesis committee reviews these summaries and sends the student a letter summarizing their status in the program. Students who are failing to make satisfactory progress are expected to correct any deficiencies and move to the next milestone within one year. Failure to do so will result in dismissal from the program.

Ph.D. Dissertation

Within 4 years after entering the Ph.D. program, the student is expected to complete the thesis research; the student must have the results of the research accepted or published in peer-reviewed journals. Upon submitting a written thesis and public defense and approval by the committee, the student is awarded the Ph.D. degree. The defense will consist of (1) a presentation of the dissertation by the graduate student, (2) questioning by the general audience, and (3) closed-door questioning by the dissertation committee. The student will be informed of the exam result at the completion of all three parts of the dissertation defense. All members of the committee must sign the final report of the doctoral committee and the final version of the dissertation.

A minimum GPA of 16 over 20 must be maintained for graduation.

Leveling Courses (not applicable to a degree)

The Ph.D. in Environmental Engineering- Air Pollution assumes a Master degree in related fields. However, students holding any other master degree besides will be required to complete leveling courses that are designed to provide a background for the Ph.D. courses. These leveling courses are decided by the faculty committee and are not counted for graduate credits towards the Ph.D. in Environmental Engineering- Air Pollution.
