对于博士 在生态与环境科学专业，学生必须完成至少30个学分，至少18个课程学分（12个500级或以上学分）和至少6个学分论文研究。大多数EES博士学生获得的学分远远超过此。应与您的顾问协商完成学习计划，包括要修读的课程清单，并由您的整个研究生顾问委员会签署。预计该学生将组成一个研究生咨询委员会，并在学习的第二学期结束之前将该完全签署的学习计划提交给生态与环境科学研究生协调员。学生的研究生顾问委员会将至少由来自至少两个不同家庭部门的五名教师组成。要被录取为博士学位，学生必须成功完成由其研究生顾问委员会准备的
For the Ph.D. in Ecology and Environmental Sciences, the student must complete a minimum of 30 credits, a minimum of 18 course credits (12 credits 500 level or above), and a minimum of 6 credits thesis research. Most EES PhD students take many more credits than this. A program of study, including a list of courses to be taken, should be completed in consultation with your advisor and signed off by your entire graduate advisory committee. The student is expected to form a graduate advisory committee and to submit this fully signed program of study to the Ecology and Environmental Sciences Graduate Coordinator by the end of the second semester of study. The student's graduate advisory committee will be composed of a minimum of five faculty from at least two different home departments. To be admitted to candidacy for the Ph.D., the student must successfully complete a comprehensive examination consisting of written and oral questions prepared by her/his graduate advisory committee. The structure of the written and oral exam depends largely on the traditions of the advisor's home department. Timing and grading also depend on the advisor, advisory committee, and home department traditions. Students should work with their advisor and graduate advisory committee members to understand the structure and expectations of the comprehensive exams. In general, students are expected to take the written component of the comprehensive examination by the end of the second year of study. The Graduate School provides relevant forms related to comprehensive exams that students should make themselves aware of and complete. Graduate School rules regarding failed exams apply. Prior to initiation of the dissertation research, each student should prepare a written thesis proposal and present a thesis-proposal seminar to their graduate advisory committee. This proposal may or may not be a public seminar, depending on the advisor's preferences. The seminar should discuss the objectives, hypotheses, background, literature and methods of the proposed research investigation.
