The Department of Biological and Environmental Sciences offers a Master of Science degree in Biological Sciences and a Graduate Certificate in Environmental Sciences. The graduate programs in biology are designed to provide opportunities for students to pursue advanced training in particular fields of biology, to advance their professional goals, or to prepare students for entry into doctoral or professional health programs. The Master of Science degree in Biological Science offers both thesis and non-thesis options. The program is available face to face or online for students completing the non thesis option. Students wanting to enroll in the thesis option are encouraged to contact faculty members with similar research interests. Faculty research interests within the department include behavioral ecology, environmental science, microbiology, neuroscience, molecular, cellular and developmental biology, as well as wildlife ecology and conservation.
Programs of Graduate Work
Admission to a graduate program is granted by the Dean of Graduate Studies upon the recommendation of the department. Applicants must meet the following requirements for admission in addition to meeting the general university requirements in Biological Science.
Students accepted in the graduate programs of the Department of Biological and Environmental Sciences are expected to follow all of the rules and procedures established by the Department. Students in all programs except the graduate certificate must pass a final comprehensive examination. The final comprehensive exam will normally be an oral exam administered by the student's advisory committee, with other departmental graduate faculty invited to participate, as well as faculty from a minor department when appropriate. Oral exams can be scheduled by the student's advisor only after a completed thesis or non-thesis paper has been reviewed by the advisory committee.
Note: The Department reserves the right to suspend from the program any student who in the judgment of the departmental graduate committee, does not meet the professional expectations of the field.
