Subject abbreviation: ENTX David A. Eastmond, Ph.D., Chair and Program Director
Professors
GRADUATE PROGRAMThe interdepartmental graduate program in Environmental Toxicology has participating faculty from the departments of Biochemistry, Cell Biology and Neuroscience, Chemical and Environmental Engineering, Chemistry, Entomology, Environmental Sciences, Philosophy, and Plant Pathology, as well as scientists from the Air Pollution Research Center and the Division of Biomedical Sciences. The goal of the program is to train toxicologists capable of directing research in areas of environmental toxicology. Areas of specialization include biochemical toxicology and chemical toxicology. To attain this goal, a three-tiered curriculum has been designed whereby students are expected to complete
The program stresses the importance of innovative and independent laboratory research as the major component of the student's education. For admission into the graduate program in Environmental Toxicology, a student must have a B.A. or B.S. degree from an accredited institution and an academic record which satisfies the minimum admission standards established by the Graduate Division, UCR. In addition, results from the GRE General Test (verbal, quantitative, analytical) must be submitted at the time of application. Although no specific undergraduate degree specialization is required, applicants should have adequate backgrounds in the basic physical sciences such as chemistry, physics, and mathematics as well as in the biological sciences. Normally, students admitted to regular standing have satisfied all prerequisite course work. Under special circumstances, students who have not completed all undergraduate requirements may be admitted provided that these deficiencies are corrected early in their graduate studies. Deficiencies must be corrected by taking the appropriate course work if undergraduate or other previous training has not included equivalent courses to the following:
BCH 110A-BCH 110B or BCH 100, BCH 110C BIOL 107A CHEM 001A-CHEM 001B-CHEM 001C, CHEM 005, CHEM 112A-CHEM 112B-CHEM 112C CHEM 109 or CHEM 110A, CHEM 110B or CHEM 109 and BCH 184 (exceptions depend on biochemical or chemical emphasis) MATH 009A-MATH 009B PHYS 002A, PHYS 002B, PHYS 002C STAT 100A and STAT 100B; or STAT 120A-STAT 120B Students who meet all the undergraduate entrance requirements should be able to complete the core Environmental Toxicology requirements in the first year and most electives by the end of the second year. Laboratory Rotation All Environmental Toxicology students participate in laboratory rotation through enrollment in ENTX 201L. Students spend time in one laboratory per quarter familiarizing themselves with research techniques utilized in the laboratory of an Environmental Toxicology faculty member. Rotation laboratories are chosen in consultation with the graduate advisor and individual faculty members. Students may enroll in up to three quarters of laboratory rotation before declaring a major professor. Students who wish to declare a major professor after one quarter are not required to enroll for additional laboratory rotation. The major professor serves as chair of the student's Guidance and Dissertation Committees. Guidance Committee Each Environmental Toxicology graduate student establish a guidance committee which participates in the annual student progress evaluation procedure and advise the student on curriculum and research. The committee consists of the major professor plus at least two other faculty, one of whom must be a member of the Environmental Toxicology Program. Each student, in consultation with the major professor, nominates the members of the guidance committee. The committee must be named by the end of the quarter in which the student selects a major professor. The composition of the guidance committee must be approved by the curriculum and student affairs committee. Master's DegreeStudents enrolling in the master's degree program must meet the requirements for the Plan I of the UCR Graduate Council, take core courses as described above, and submit an acceptable thesis.Thirty-six (36) units are required, of which 24 must be in graduate-level courses. No more than 12 units of ENTX 290, ENTX 297, and ENTX 299 may be used to satisfy the unit requirement. All students must enroll in the Environmental Toxicology seminar (ENTX 270) each quarter, although no more than 3 units from seminar courses can be accrued towards degree credit. A final draft of the thesis is to be given to the thesis committee two weeks before the final oral examination. A final oral examination consists of an open research seminar, presented by the candidate and advertised to all the students and faculty in the Environmental Toxicology Program. Following the seminar, the student is questioned by the guidance committee on the thesis research and on matters related to the general field of the thesis research. Normative Time to Degree 6 quarters Doctoral DegreeStudents must meet general university requirements of the Graduate Division as found in the Graduate Studies section of this catalog. Beyond the required core sequence, all students must enroll in the Environmental Toxicology seminar (ENTX 270) and complete a program of courses to be approved by the guidance committee. All course work schedules are submitted to the graduate advisor for approval. The Ph.D. degree is awarded when the student passes the preliminary and qualifying examinations and demonstrates an ability to do original research by preparation and submission of an acceptable dissertation.Preliminary Examination The preliminary examination is a standardized, written test generally offered once a year prior to the beginning of the fall quarter. Students normally take it following the completion of the core curriculum. The examination must be satisfactorily completed in order to enroll for the seventh academic quarter in the Ph.D. program. The examination consists of questions related to environmental, organismal and suborganismal aspects of toxicology. These questions are designed to test the student's ability to synthesize and integrate concepts in toxicology, rather than merely reiterate the material covered in the Environmental Toxicology core curriculum. The examination is administered by a committee consisting of the faculty members involved in teaching the core curriculum. On the basis of the results of this examination, the committee recommends appointment of a faculty qualifying committee, additional course work in specific area(s) of weakness, transfer to a terminal master's program, or withdrawal from the program. In exceptional circumstances, the preliminary examination can be taken a second time. Qualifying Examination The qualifying examination is an oral examination conducted by the qualifying committee. The qualifying committee, appointed by the graduate dean from nominations made by the faculty, is composed of the student's major professor and four additional members, one of whom must be from outside the Graduate Environmental Toxicology group. The oral examination includes the student's area of specialization and research field as well as general subjects at the discretion of the qualifying committee. The qualifying examination must be successfully completed by the end of the ninth quarter of full-time enrollment in the Ph.D. program. Under exceptional circumstances, the qualifying examination may be taken a second time. Upon successful completion of the qualifying examination, the student is advanced to candidacy. Dissertation and Final Oral Examination A dissertation committee composed of at least three members is appointed by the graduate dean shortly after advancement to candidacy. A dissertation acceptable to all committee members must be submitted based upon independent, original research. A final draft of the dissertation is to be given to the committee two weeks before the dissertation defense seminar. Before approval of the dissertation, students are required to present their research orally at a thesis defense seminar. The seminar must be advertised to the campus community and is open to all who wish to attend. Following the seminar, the student is questioned by the dissertation committee on the thesis research and on matters related to the general field of the thesis research.
