1. Program description

ÁùºÏ±¦µä the program

The ES&H Graduate Program consists of approximately 60 faculty members and over 50 graduate students. The faculty represent a broad spectrum of research, teaching interest, and departments/colleges at the University of ÁùºÏ±¦µä, Reno, and several scientists from the Desert Research Institute (DRI) and faculty from other local educational and research institutes.

The Doctor of Philosophy (Ph.D.) graduate degree program and the Master of Science (M.S.) degree program of ES&H helps the student to think critically and independently; comprehend the processes of science and effectively apply scientific principles and professional procedures; attain proficiency in the current knowledge in the respective fields; develop competence in technical skills and tools required in their disciplines.

Mission statement

The mission of the UNR Environmental Sciences & Health graduate (ES&H) program is to provide training to scientists in the following disciplines: environmental chemistry, environmental toxicology; ecological toxicology; environmental microbiology. Environmental chemistry focuses on measurements and environmental processes affecting chemicals in the environment. Environmental toxicology focuses on biochemical and cellular toxicology, with a particular emphasis on the impact of contaminants on humans. Ecological toxicology combines the disciplines of wildlife toxicology and conservation biology to understand how contaminants affect populations and ecosystems. Environmental microbiology is the study of how microbes interact with the environment and each other, including their effects on the landscape, the spread of viruses and bacteria, the distribution of algae, fungi, and parasitic organisms, and the associated implications for human health and the environment. Environmental microbiology also researches how microbes can be used to solve global problems. The program works under the premise that students must have a solid environmental sciences core curriculum and be flexible to draw upon the interdisciplinary knowledge base of the program's faculty members. This flexibility permits the student to design a curriculum to meet their interest and professional goals.

Program/student learning outcomes (SLOs)

1. They understand the theoretical and experimental basis for studying contaminants in the environment and their effects on humans and ecosystems.
2. Knowledge of the design and use of field instrumentation, computer models, data analysis, and laboratory procedures for environmental chemistry and toxicology research and monitoring.
3. Ability to explain ideas and results through written, numerical, graphical, spoken, and computer-based forms of communication.
4. The ability of the ES&H program to respond to changing interdisciplinary needs of students.

• At least 18 credits must be taken at the 700-level: These credits may not include dissertation credits or credits obtained during undergraduate study.
• Up to 18 credits of 700-level course work from a master's degree program may be applied to this requirement: No more than 24 credits of course work (with grades of B or better) from a master's degree program or previous post-baccalaureate graduate studies program, maybe allocated toward the doctoral degree. An exception is for students who hold an MPH degree from UNR, or an accredited institution, 32 credits of course work of B or better may be allocated toward the doctoral degree.

Candidates for the Ph.D. degree must register for at least 24 dissertation credits and must submit a satisfactory dissertation to the examining committee: 12-30 dissertation units may be applied toward completion of doctoral degree

1. A maximum of 24 credits must come from dissertation work;
2. Any exception to the minimum 24 dissertation credits requires the advance written approval of the program director and the graduate dean

All requirements for the doctoral program, excluding prerequisite graduate course work or master's degrees, must be completed within eight years.

Total credits required for doctoral degree: 60

• 600-level credits: 18
• 700-level credits: 18
• Thesis credits: 24

The Environmental Sciences & Health program course requirements have been selected with a minimum number of required courses to allow the student an opportunity to design a curriculum to meet each student's disciplinary interests and professional aspirations.

Prerequisite courses

Degree in related science, including calculus and chemistry, and additional coursework in organic chemistry, biology, and physics. Other courses are accepted at the discretion of the Director.

Committee membership

For a doctoral degree, after twelve graduate credits (approximately two semesters), the student selects a committee chair, and the student and chair arrange the appointment of the remaining four members of the committee. All committee members must be listed on the Graduate Faculty. The committee and the Director of the Environmental Sciences program supervise the student's study and examinations.

The Graduate Dean makes formal approval of the student's advisory/examining committee. Students may request the appointment of a committee member from the faculty of another university or a relevant discipline or profession, provided the prospective member has achieved a record of distinction. In addition to the committee chair, at least four members will be from the ES & H Program, at least one will be from a department in a field related to the student's major, and at least one will be a Graduate School representative from the graduate faculty.

Required courses

All students must have one graduate course in statistics and attend the NRES 790 Environmental Sciences seminar or other appropriate seminars (4 credits for the Ph.D.). Regarding transfer credits for doctoral students who have completed an M.S. program, a maximum of 24 credits of course work from a completed master's degree program or previous post-baccalaureate graduate studies program or 32 credits from an accredited MPH Program may be applied toward the doctoral degree. All students must take 4 of the 13 courses listed below. A student's advisor and committee members can recommend substitutions with a specific research focus.

Additional course requirements

In addition to the Core Courses listed above, all ES&H students must take:

Suggested elective courses

Note on elective courses:

Each student's program of study is based on the disciplinary track they have chosen. Elective courses may be selected from a variety of departments, including but not limited to:

• Atmospheric Sciences (ATMS)
• Biochemistry (BCH)
• Chemistry (CHEM)
• Civil and Environmental Engineering (CEE)

By the conclusion of the first year, the student's advisory committee will collaborate on the rest of the program of study. The Ph.D. student's program of study must include at least 60.

Comprehensive examination for admission to doctoral candidacy

Written examination:

The written examination is a general examination of environmental science and health. The examination has at least 5-7 questions. The student's committee develops the written questions in the general area of the student's courses and program. For purposes of consistency, the program director will need to approve each written exam at least one week before the exam is given to the student.

The exam will be given for 8 hours and proctored by the student's committee chair. It will be a closed book exam.

The following provides examples of how the exams could be structured.

• A student studying phosphorus, sediment, and Lake Tahoe might be expected to understand spectroscopic methods, sorption processes, impacts of nutrients on watersheds, soil chemistry, and the basis for regulatory actions regarding nutrients.
• A student studying gas exchange in plants might be expected to know atmospheric measurement processes, plant physiology, soil-plant relationships, and global changing issues and impacts.
• A student focused on public health might be expected to know epidemiology, toxicology, biochemistry, and environmental contaminants that affect human health.

Oral examination:

The oral examination focuses on the student's knowledge of the specific area of research and involves presenting no more than 13 research slides followed by questions. The committee questions are generally in the particular area of research and designed to determine how well the student understands their research and their ability to conduct research.

Suggested elective courses

Elective courses

Each student's program of study is based on the disciplinary track they have chosen. Elective courses may be selected from a variety of departments, including but not limited to:

• Atmospheric Sciences (ATMS)
• Biochemistry (BCH)

Graduate School academic requirements

All graduate students must maintain a cumulative graduate GPA of 3.0. If their GPA drops below 3.0, they are placed on probation or dismissed. Undergraduate courses will not count towards graduate GPA.

Probation: Students whose cumulative graduate GPA is .1 to .6 points below that need a 3.0 GPA are put on probation. Students are placed on academic probation for one semester. If they fail to raise their cumulative GPA to 3.0 by the end of one semester, they are dismissed from their graduate program. Thesis, dissertation, S/U graded credits, and transfer credits have no impact on a student's GPA.

Dismissal: Students whose cumulative graduate GPA is .7 or more grade points below that needed for a 3.0 GPA are dismissed. Dismissed students are no longer in a graduate program but may take graduate-level courses as a Grad Special. Students wishing to complete their degree must obtain approval to take graduate-level courses, raise their graduate GPA to at least 3.0, and then re-apply to a graduate program. Any courses taken to raise their GPA will be included in the graduate special/ transfer credit limitation (9 credits for master's degrees).

3. Transfer credits

These are credits transferred from another institution. Credits completed at UNR in another program or as a graduate special do not need to be transferred. Transfer credit is requested on the Graduate Credit Transfer Evaluation Request form on the Graduate School website. And must be signed by the student, major advisor, and graduate director. Transfer credits applied to a master's program must comply with the time limitation on master's work (6 years). Thus, if a student took a course five years before admission, they would have to complete the degree within one year for the course to apply to the degree. Credits from a completed master's degree will be exempt from the 8-year time limitation for those students earning a doctoral degree.

6. Graduate assistantships

Include information on availability and policy for graduate teaching and research assistantships, along with requirements.

All graduate students holding an assistantship (teaching GTA or GRA) are ÁùºÏ±¦µä residents for tuition purposes. To be eligible for an assistantship, students must be admitted to a degree-granting program and be in good academic standing. The student must have an overall GPA of at least 3.0 and be continuously enrolled in at least 6 graduate-level credits (600-700) throughout the assistantship. Non-resident tuition is only waived for the duration of the assistantship.

State-funded assistantships (GTA/GRA) may be held for a maximum of three (3) years for master's degree students and five (5) years for doctoral degree students.

Please also include links to the most updated information on graduate assistantship on the graduate school website:

7. Health insurance

All domestic degree-seeking graduate students enrolled in six or more credits (regardless of the course level) in a semester will be automatically enrolled and billed for the University-sponsored health insurance for each eligible term (fall & spring/summer). Suppose a student has other comparable coverage and would like to waive from the student's health insurance. In that case, it is the student's responsibility to complete the  before the deadline. A health insurance waiver is good for the current academic year only if approved. A new waiver must be submitted each academic year. All international graduate students must carry student health insurance, and the cost will be automatically added to your student account. Any international graduate students with insurance questions must contact the  directly.

Graduate medical, dental and vision insurance

8. Leave of absence

Continuous enrollment

To maintain "good standing," all graduate students are required to enroll in a minimum of three (3) graduate credits each fall and spring semester until they graduate. All students holding assistantships (whether teaching or research assistantships) are required to enroll in a minimum of six (6) graduate credits each semester they hold the assistantship. International students may be required to enroll in nine graduate credits each fall and spring semester, depending on their visa requirements.

Leave of absence

Students in good standing may request a leave of absence by completing a leave of absence form available on the Graduate School's student forms page during which time they are not required to maintain continuous registration. Usually, a leave of absence is approved for one or two semesters. The leave of absence request may be extended by the student filing an additional leave of absence form. Students applying for a leave of absence should not have any "incomplete" grades, which could be changed to "F" and have a detrimental impact on their cumulative GPA. Requests for leave of absences must be received by the Graduate School no later than the last day of enrollment for the semester the leave is to begin.

Reinstatement

When a student has been absent for one semester or more without an approved leave of absence, he or she may request reinstatement via the Reinstatement form (available on the Graduate School's student forms page). This form allows the program to recommend the student be re-admitted to their graduate program based on their previous admission OR require the student to re-apply for access, requiring students to submit a new application for admission and pay the application fee. The Notice of Reinstatement to Graduate Standing must be received by the Graduate School no later than the last day of enrollment for the semester the reinstatement is to begin.

9. Graduate Student Association

The Graduate Student Association (GSA) represents all graduate students and promotes the welfare and interests of the graduate students at the University of ÁùºÏ±¦µä, Reno. The GSA works closely with appropriate university administrative offices, including the Graduate School and Student Services, and reports to the President of the University. The GSA government functioned through the Council of Representatives, Executive Council, and established committees.
