Honors in the Biology Major
Requirements
- Student typically will have worked on a research project for 2 semesters (or 1 semester + summer session) minimum, before applying for honors
- Student must have an average GPA of 3.25 (college policy)
Application Process
- Students should discuss with their research mentor and submit an official Letter of Intent to the Biology Chairperson by the first week of their senior year, or sooner.
- The letter of intent should include a summary of research results (realized and projected), as well as significance of the research and any projects in progress at the time of submission.
- Applications will be evaluated by the Biology faculty.
- Students nominated for honors will be notified by the Biology Chairperson.
Completion Process
- At the time of nomination, each candidate will be assigned an honors thesis committee of two Biology faculty members, in addition to their faculty mentor. This committee will be available for guidance and to help ensure that milestones are met in a timely manner.
- Milestones will include a thorough literature review, written drafts of the introduction, methods, and results sections, including draft figures, and a final discussion section, as well as preparation of a public seminar.
- The candidate must complete a written thesis of their work. It is expected that the student will spend part of their final semester or directed research writing the thesis.
- The written thesis will be due to the mentor by Monday in the 3rd week of February.
- The revised honors thesis will be due to the committee by Monday in the 2nd week of March.
- The thesis will be reviewed by committee and returned to the student by Monday the 4th week of March, and final revisions must be submitted by the first week of April.
- Honors candidates will also give a presentation on their research to be scheduled on or about April 15. These presentations will last approximately 25 minutes, with 5 minutes for questions.
- Honors grades are Pass/Fail and reported to the registrar by the Chair. The chair will inform the students of their grade when it is decided upon by the committee.
Minor
Introductory Level Biology
Students must select one course from the list below:
| BIO 105 | Marine Biology | 4 units |
| BIO 110 | Introductory Biology: Biodiversity, Ecology, and Evolution | 4 units |
| BIO 115 | General Zoology | 4 units |
Additional Biology Electives
Choose four additional biology courses, including BIO 130, or any 200- or 300-level Biology courses, two of which must be taken in the Occidental College Biology Department. Two-unit courses may not apply to this requirement. Independent Studies and Advanced Placement credit may not count toward the minor.
