Biology
Overview
Biology is a rapidly expanding, multifaceted discipline, full of possibilities for undergraduate research and for stimulating graduate study and employment after Occidental. Within an evolutionary framework, our program investigates the interactions between molecules, cells, organisms, populations, and ecosystems that constitute life on earth. Interdisciplinary and integrative by nature, the biology program at Occidental engages both majors and non-majors in a curriculum that emphasizes laboratory and field investigation. Our students are encouraged to collaborate with faculty mentors, whose research employs current methods in addressing questions from the molecular to the global in scale. Students acquire skills from careful observation through hypothesis formulation and experimental design to formal oral and written presentations of results. After participating in the biology program at Occidental College, students are prepared for rewarding work and lifelong learning, armed with the tools necessary to understand large complex data sets and help explain the intricacies of living systems. This rigorous program provides our students with the training to enter the work force after graduation and/or transition to an advanced degree program. After completing the major, many students elect to take graduate training toward the PhD. in biological sciences or doctorates of medicine, veterinary medicine, pharmacy or dentistry. Many of our students complete Masters programs in Biological Sciences, teaching, environmental health and safety, and resource management. Receiving a degree in Biology at Occidental College enables our students to excel in any post-baccalaureate professional pursuit.
The Department of Biology is housed within the Bioscience building which is contiguous with the Moore Laboratory of Zoology. Facilities include the bird and mammal collections (70,000 specimens) of Moore Laboratory, greenhouses, facilities for microscopy (scanning and transmission electron and fluorescence), a tissue culture suite and fluorescence-activated cell sorter, fully-equipped molecular biology laboratories, field vehicles, and three research vessels for nearshore marine studies and SCUBA diving. Because of its proximity to the Mojave Desert, the Santa Monica, San Gabriel, and San Bernardino Mountains, and seacoast, Occidental College is ideally suited for field and laboratory studies of environmental biology.
Biology majors must complete these courses within the Biology Department at Occidental: at least two of the four 200-level courses and at least two 300-level electives. A course used to fulfill one requirement cannot fulfill another major requirement. Two-unit transfer courses and AP exams or placement exams do not meet requirements for the major. The Biology Department does not accept online coursework for transfer credit toward the Biology Major.

HONORS
The Honors Program at Occidental College is designed to allow the superior student’s attention to be focused on a directed investigation for a sustained period of time. It is expected that students admitted to the College Honors Program will have established themselves as outstanding prospects for individualized work in the department of their major and will also have established themselves as doing work of very high quality in all that they have undertaken at Occidental. Student admission to the College Honors Program will be by formal action of the faculty in the student’s major department (taken from the College Catalogue statement on Honors).
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
- Student should discuss with their research mentor and submit an official Letter of Intent to the Biology Chairperson by the beginning 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 4th week of February.
- The revised honors thesis will be due to the committee by Monday in the 3rd week of February.
- The thesis will be reviewed by committee, and final revisions must be submitted by the last day of March.
- Honors candidates will also give a presentation on their research during the week of April 15. These presentations will last approximately 15 minutes, with 5 min 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.
