PhD in Chemistry with an Environmental Chemistry Track
I. Track description
The Ph.D. program in Environmental Chemistry is situated within the current doctoral program in the Department of Chemistry and Biochemistry. This track will prepare students with an interest in the chemical aspects of environmental science with coursework and research experience at the doctoral level. Graduates of the program will have developed a strong expertise in both environmental science and chemistry, and will therefore be able to find employment in these areas in industry, government and academia.
The proposed track consists of both academic classes and research. The requirements of the track are similar to those that presently exist for doctoral students in chemistry. The difference between the current doctoral program and the new track lie in the requirement that the majority of the coursework and the thesis research be in the general area of environmental chemistry.
II. Rationale, types of students, expected numbers of students in the first five years, community need/relevance
There is an increasing need for doctoral training in Environmental Science based both on surveys of employers and on student interest. Thus many universities are at present developing and implementing interdisciplinary doctoral level programs in Environmental Science and related fields. The model chosen for the FIU doctoral Environmental Science program is for the Environmental Science Program (housed in SEAS) to work with science departments, namely Biological Sciences, Chemistry and Biochemistry, and Earth and Environment, to develop Environmental Science majors within their existing Ph.D. or M.S. programs. This will help in recruiting high quality doctoral students to populate those majors. FIU has a well-established reputation in the field of Environmental Science, and through SERC and faculty in the science departments has gained significant research support and infrastructure to support such interdisciplinary programs.
The types of students we expect to enter this program are those who have a current interest in the chemical and biochemical aspects of environmental science and wish to earn a doctoral degree indicating specific expertise in these areas. The program fits well with current areas of emphasis of the University. Both local students and those from out of area will be attracted to this program because of the combination of specific expertise of current faculty in areas of environmental science and the additional training they will receive in chemistry at the graduate level. There is a strong local market for students with advanced training in the general area of environmental science. As a consequence, graduates of this program should find that there is a demand for people with their skills. The increasing importance of the environment on the national level means that there should also be a general demand for students with an interest and training in environmental science and specific expertise in environmental chemistry and biogeochemistry.

- At least one elective. The list of approved electives is maintained by the Chemistry and Environmental Science Major Graduate Committee. This committee consists of the Environmental Science Graduate Program Director, the Chemistry and Biochemistry Graduate Program Director, and two Departmental faculty members active in research in environmental science.
- Full time graduate students are required to register for one credit of CHM 6940 (Supervised Teaching) each semester they serve as a teaching assistant.
- Full time graduate students are required to register for one credit of CHM 6935 (Graduate Seminar) and one credit of CHM 6936 (Chemistry Colloquium) each fall and spring semester.
- At least one credit of CHM 6936 (Chemistry Colloquium) is required. Each student must present a seminar on their proposed research at the colloquium for a letter grade by the end of their third semester of graduate study.
- At least eight credit hours of CHM 7910 (Dissertation Research) involving independent dissertation research under the direction of a faculty member in the Department.
- At least 20 credits of CHM 7980 (Ph.D. Dissertation) is to be taken after the student has advanced to candidacy.
- A maximum of 36 credits may be transferred from another graduate program with the approval of the Graduate Committee. However, only six credit hours can be counted towards the formal post-baccalaureate coursework. Students must elect an appropriate course load in accordance with their research topic, and in agreement with their Graduate Committee and the Departmental Graduate Advisor.
- 12 credit hours of required classes including four of the following six environmental chemistry core courses, each of which is worth three credit hours.
- Satisfactory completion of cumulative exams. The students will begin taking the cumulative examinations after completing the proficiency requirements but no later than the beginning of the student’s second semester. Six exams, each lasting three hours, will be given each year. The student must pass four out of 10 consecutively offered exams for admission to candidacy. Cumulative exams in the area of Environmental Chemistry will be added to existing specialties.
- Satisfactory presentation and defense of an original research proposal, and satisfactory completion of a preliminary oral examination. The presentation and examination occur consecutively in a single session and must be completed before the end of the fifth semester (excluding summers). The examination will be conducted by the Dissertation Committee, be based on the student’s dissertation research, and include questions from the student’s major field and cognate fields. After fulfilling this requirement, passing the cumulative examinations, and completing all required course work, the student advances to candidacy.
- Satisfactory public presentation and defense of a research dissertation, evaluated by the Dissertation Committee. The student’s Dissertation Committee will consist of the research advisor (an FIU graduate faculty member who holds dissertation advisor status), a member from outside the Department or School but within FIU, a randomly selected member appointed by the Graduate Program Director from the Department’s graduate faculty, and at leat two additional committee members with expertise in the student’s research area. At least three members of the Dissertation Committee, including the major research advisor, must be graduate faculty members from the Department of Chemistry and Biochemistry, and at least two of these three members must be tenured. The Committee may include additional members, but they will be non-voting.
