Biochemistry

Overview

Biochemistry explores the cell's molecular components and the chemical changes characteristic of living organisms. A thorough foundation in both biology and chemistry forms the core of biochemistry. Occidental's biochemists seek to use their scientific knowledge and broad education in the liberal arts to advance the public good and improve health care, economic opportunities, environmental stewardship, national security, as well as expanding human understanding through their teaching and research.

The core portion of the Biochemistry major includes BIO 130, the two biochemistry classes BIO 349 and CHEM 350, and the Biochemistry Senior Seminar, BICH 490. Classroom activities are supplemented by extensive laboratory experience involving the design, execution, and interpretation of experimental results. Biochemistry graduates generally elect to pursue graduate training toward a Ph.D. in Biochemistry or areas in Cell and Molecular Biology, a doctorate in the health professions, employment in the biotechnology field, or a career in education. Students planning on pursuing a Ph.D. are advised to take several more courses including the advanced Cell and Molecular offerings in Biology, and advanced Chemistry courses in Chemistry, to broaden their education. Biochemistry students are strongly encouraged to pursue their particular interests through an independent study-research project (BIO 395 or CHEM 395). The Biochemistry program is eager to accommodate the foreign study aspirations of its majors; however, due to the curriculum's sequential nature, careful advance planning is required.

Students wishing to declare the Biochemistry major should have completed two Biology and two Chemistry classes with at least a 2.7 GPA in these classes and arrange for the discussion of their schedule with one of the Program's advisors.

Requirements

Major

Biology Component

Students must complete five courses as detailed below:

Chemistry Component

Mathematics Component

Physics Component

Senior Seminar

Students are to enroll in BICH 490 (2 units) each semester of their senior year.

Honors in the Major

In addition to the requirements for College honors (see the Awards section), the student will successfully defend a written thesis based upon the outcome of his or her laboratory research effort as an undergraduate as detailed below.

Guidelines for College Honors in Biochemistry

Requirements

• Students typically will have worked on a research project for at least 2 semesters (or 1 semester + summer session), before applying for honors.
• Students must have an average GPA of 3.25 (college policy).

Application Process

• Students should discuss doing Honors with their research mentor, get their approval, and submit an official Letter of Intent to the Biochemistry Chairperson(s) by the beginning of their senior year, or sooner.
• Letters 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 biochemistry program faculty.
• Students nominated for honors will be notified by the Biochemistry Chairperson(s).

Completion Process

• After nomination, by September 30th each candidate will select an honors thesis committee of two Biochemistry program faculty members (excluding Chairperson(s)), in addition to their faculty mentor. This committee will be available for guidance and to help throughout the honors process.
• Mentors will check in with Chairperson(s) during the first week of classes in the Spring semester to confirm that honors candidates have enough content to proceed.
• Candidates will work with their mentor, committee members, and Chairperson(s) to establish a timeline for the completion of the written thesis and honors presentation. This timeline must conform to the guidelines below and any college requirements for the completion of honors. This timeline is due to the Chairperson(s) before March.
• Requirements for receiving honors:
  • The candidate must complete a written thesis of their work. Draft deadlines must allow ample time for revision. The final thesis must be completed before the honors presentation.
  • Honors candidates will give a presentation on their research. These presentations will last approximately 15-20 minutes, with 5-10 min for questions (20-30 minutes total). Honors presentations are typically scheduled during Senior Seminar in the middle of April.
• Honors are recorded as Pass/Fail and are reported to the registrar by the Chairperson(s). The Chairperson(s) will inform the students of their performance when it is decided upon by the committee. The deadline for submitting honors results is announced by the registrar in the yearly academic calendar (usually end of April).

Second-Stage Writing

Students should familiarize themselves with the second-stage writing requirement at the time of declaring the major. Students majoring in Biochemistry will satisfy this requirement by completing an in-depth research paper  during the fall semester of BICH 490 (Senior Seminar). This paper is evaluated by the instructors for BICH 490 and by members of the Biochemistry Advisory Committee. Students who do not fulfill this requirement during BICH 490 must consult with the Biochemistry program Chair about available alternatives. This may mean enrolling in CWP 201 (passing with a C or better).  Students can meet with the Biochemistry program Chair for more detailed information about the process of fulfilling the second-stage writing requirement.

Comprehensive Requirement

The student must pass the Graduate Record Examination in Biochemistry at the 50th percentile rank or the American Chemical Society undergraduate examination in Biochemistry at the 50th percentile rank. The student will also satisfactorily write a research paper and present a seminar during the senior year on an area of current research in the field of Biochemistry to an audience of Occidental students and faculty. A student can earn a Pass with Distinction in Biochemistry with a 75th percentile rank and a distinguished paper and seminar presentation.

Transfer Credit Policies

The Biochemistry Program policy on transfer credit conforms to College policy. Students should reference the Transfer Credit section for details.
