ENVIRONMENTAL SCIENCES GRADUATE PROGRAM
Subject abbreviation: ENSC _____________, Director
Professors
Recent years have seen a dramatic increase at both the state and national level in the need for individuals trained to handle complex environmental problems. Numerous environmental concerns associated with pesticide application, waste disposal, air pollution, and other health-threatening activities have prompted regulatory agencies to develop strategies for the use and disposal of potentially hazardous materials. This situation has created a need in government and industry for scientists trained in a broad spectrum of disciplines. Well-trained environmental scientists are in demand at all levels of the regulatory process. The Interdepartmental Graduate Program in Environmental Sciences mobilizes the expertise of UCR's faculty by providing advanced educational opportunities for students interested in pursuing research, teaching, and professional careers in the wide spectrum of activities relevant to environmental science. Students normally come to the program having completed an undergraduate degree in environmental science, in a related discipline such as atmospheric science, aquatic science, earth science, economics, hydrology, soil science, or one of the basic sciences such as biology, chemistry, or physics. Students are expected to have completed the following courses or their equivalents before entering the program, or to make up the deficiency early in their graduate studies. CHEM 001A, CHEM 001B, CHEM 001C or equivalent PHYS 002A, PHYS 002B,
PHYS 002C or equivalent
Students may conduct research in any environmentally related area of interest to a sponsoring faculty member. Examples are: • Kinetic and products studies of the atmospheric chemistry of volatile organic compounds
There is no foreign language requirement for the program. The Department of Environmental Sciences offers the M.S. degree under the Plan I (Thesis) and Plan II (Comprehensive Examination) options. Course Work 1. Transport and Fate of Chemicals CHEM 246/ENSC 200/ENTX 200 (Fate and Transport of Chemicals in the Environment)
2. Interactions and Cycling in the Biosphere ENSC 208/ENTX 208/SWSC 208 (Ecotoxicology)
3. Environmental Policy and Management ENSC 201 (Environmental Management)
Plan I (Thesis) Students must complete a minimum of 36 quarter units of graduate and upper-division undergraduate courses in or significantly related to Environmental Sciences. At least 24 of the 36 units must be graduate courses. Students must take one course each from (1) and (2) above and two courses from 3. A maximum of 12 of the 24 graduate units may be in graduate research for the thesis. Each quarter, students must enroll in the seminar course CHEM 257/SWSC 257 and give an oral presentation at the annual student seminar or retreat. No more than two units of CHEM 257/SWSC 257 may be applied toward the 24-unit graduate requirement. Students must write a thesis that is accepted by the thesis committee members and pass an oral defense of the thesis. Plan II (Comprehensive Examination) Students must complete a minimum of 36 quarter units of graduate and upper-division undergraduate courses in or significantly related to Environmental Sciences. At least 18 of the 36 units must be graduate courses. Students must take at least four graduate courses from the three core areas listed above, including one course each from (1) and (2) above and two courses from 3. Students may count no more than 2 units of CHEM 257/SWSC 257 toward the required 18 units and no units from graduate research for thesis or dissertation. Students take a comprehensive written examination that covers fundamental topics in environmental sciences. The written examination, which is three to four hours long, is prepared and evaluated by a committee appointed by the program chair. The examination is taken during the latter part of the final quarter in the M.S. program. Students must wait at least eight weeks before retaking a failed examination. Students failing the examination twice are dismissed from the program. Course Work Upon acceptance to the program, the student selects a course work advisory committee consisting of three members of the faculty participating in the graduate program to assist in the planning of the individualized curriculum. A course work study plan should be filed with the graduate advisor by the second quarter after admission. Students must take one course each from (1) and (2) below and two courses from 3. 1. Transport and Fate of Chemicals CHEM 246/ENSC 200/ENTX 200 (Fate and Transport of Chemicals in the Environment)
2. Interactions and Cycling in the Biosphere ENSC 208/ENTX 208/SWSC 208 (Ecotoxicology)
3. Environmental Policy and Management ENSC 201 (Environmental Management)
Each quarter, students must enroll in the seminar course CHEM 257/SWSC 257 and give an oral presentation at the annual student seminar or retreat. The elective courses prescribed by the student's course work advisory committee depends on the research interests of the student. Comprehensive Written Examination Following completion of all course work, the student writes a qualifying examination prepared and administered by the written qualifying committee, which consists of five faculty members with interests in the students' line of research. The written exam may be attempted only twice. If it is failed twice, the student is redirected to the master's degree or terminated from the program. Oral Examination A student who has successfully passed the written qualifying examination may proceed with the oral qualifying examination, conducted before the oral qualifying examination committee, which consists of five faculty members, one of whom must be from outside the graduate program in Environmental Sciences. The oral examination may be attempted only twice. If the oral qualifying exam is failed twice, the student is redirected to the master's degree or terminated from the program. The written and oral exams are normally taken at the end of the second year of graduate study. Dissertation All students write a doctoral dissertation, which is read and accepted by all members of the doctoral dissertation committee, comprised of three faculty from the graduate program in Environmental Sciences. The student must pass a final, oral defense of the thesis in front of the three members. Relationship between Master's and Doctoral Programs The master's and Ph.D. programs are separate. Students who enter the Ph.D. program do not need to acquire a master's first, although students may elect to take both. Normative Time to Degree 15 quarters Career Opportunities Students trained in the Interdepartmental Graduate Program in Environmental Sciences can fill many areas of expertise needed in the state and nation.
