Integrative Biology

University of California, Berkeley

About the Program

Bachelor of Arts (BA)

Students who major in Integrative Biology (IB) will gain a broad and deep knowledge in the biological sciences as well as an excellent foundation in the biology of organisms, populations, and communities. This program may be of particular interest to students who wish to pursue graduate studies in any of these research areas. It also provides superb training for students interested in health-related professions (medicine, dentistry, veterinary medicine, physical therapy, nursing, pharmacy, optometry, etc.) or careers incorporating biology (psychology, sociobiology, forestry, wildlife conservation, environmental and resource management, law, etc.).

The department's broad range of experts includes behaviorists, ecologists, evolutionary biologists, geneticists, morphologists, paleontologists, physiologists, and systematists. 

Course of Study Overview

Students majoring in Integrative Biology choose one of two emphases: Ecology, Evolution, and Organismal Biology (Emphasis 1) or Integrative Human Biology (Emphasis 2). The lower division requirements are the same for all IB students, regardless of the emphasis. The upper division requirements differ slightly for the two emphases, but all students take lecture and lab or field lab classes from IB's three groups: Evolution and Genetics; Ecology, Behavior, and Biodiversity; Structure, Function, and Human Health. For detailed information, please see the Major Requirements tab.

Declaring the Major

In order to declare Integrative Biology as a major, students must have the following grade point averages (GPA) of at least 2.0to declare: overall Cal average of 2.0, all major requirements (lower and upper division combined) average of 2.0, all upper division major requirements average of 2.0. Students meet with a staff adviser and a faculty adviser as part of the declaration process.
 
At the time of declaration, students must be enrolled in or have completed:

Honors Program

Students with a minimum 3.3 overall GPA, a minimum 3.3 major GPA, and who are conducting biological research are encouraged to participate in the honors program. Interested students must identify an appropriate faculty sponsor who agrees to advise them on an original research project and enroll in two consecutive semesters of the honors thesis course (INTEGBI H196A and INTEGBI H196B). Honors students must present the results of their work in the form of a written honors thesis and a poster presentation. In order to graduate with honors, students must maintain the minimum required GPAs.

Minor Program

There is no minor program in Integrative Biology.

Major Requirements

In addition to the university, campus, and college requirements, listed on the College Requirements tab, students must fulfill the below requirements specific to their major program.

General Guidelines

  1. All major requirements must be taken for a letter grade.
  2. Standardized test credit (e.g., Advanced Placement) cannot be used to satisfy any major requirements.
  3. No more than one upper division course may be used to simultaneously fulfill requirements for a student's major and minor programs. Double majors and simultaneous degrees may overlap two upper division courses.
  4. Students must maintain minimum grade point averages (GPA) of at least 2.0 for: overall average of 2.0, all major requirements (lower and upper division combined) average of 2.0, and all upper division major requirements average of 2.0.
  5. A maximum of two upper division courses may be taken for major credit from outside the Department of Integrative Biology. This includes study abroad courses, as well as non-IB courses, even if they are approved electives. Visit the IB website for a list of pre-approved study abroad and elective courses.

College Requirements

Undergraduate students must fulfill the following requirements in addition to those required by their major program.

For detailed lists of courses that fulfill college requirements, please review the College of Letters & Sciences page in this Guide. For College advising appointments, please visit the L&S Advising Pages. 

University of California Requirements

Entry Level Writing

All students who will enter the University of California as freshmen must demonstrate their command of the English language by fulfilling the Entry Level Writing requirement. Fulfillment of this requirement is also a prerequisite to enrollment in all reading and composition courses at UC Berkeley. 

American History and American Institutions

The American History and Institutions requirements are based on the principle that a US resident graduated from an American university, should have an understanding of the history and governmental institutions of the United States.

Berkeley Campus Requirement

American Cultures

All undergraduate students at Cal need to take and pass this course in order to graduate. The requirement offers an exciting intellectual environment centered on the study of race, ethnicity and culture of the United States. AC courses offer students opportunities to be part of research-led, highly accomplished teaching environments, grappling with the complexity of American Culture.

College of Letters & Science Essential Skills Requirements

Quantitative Reasoning

The Quantitative Reasoning requirement is designed to ensure that students graduate with basic understanding and competency in math, statistics, or computer science. The requirement may be satisfied by exam or by taking an approved course.

Foreign Language

The Foreign Language requirement may be satisfied by demonstrating proficiency in reading comprehension, writing, and conversation in a foreign language equivalent to the second semester college level, either by passing an exam or by completing approved course work.

Reading and Composition

In order to provide a solid foundation in reading, writing, and critical thinking the College requires two semesters of lower division work in composition in sequence. Students must complete parts A & B reading and composition courses in sequential order by the end of their fourth semester.

College of Letters & Science 7 Course Breadth Requirements

Breadth Requirements

The undergraduate breadth requirements provide Berkeley students with a rich and varied educational experience outside of their major program. As the foundation of a liberal arts education, breadth courses give students a view into the intellectual life of the University while introducing them to a multitude of perspectives and approaches to research and scholarship. Engaging students in new disciplines and with peers from other majors, the breadth experience strengthens interdisciplinary connections and context that prepares Berkeley graduates to understand and solve the complex issues of their day.

Unit Requirements

  • 120 total units

  • Of the 120 units, 36 must be upper division units

  • Of the 36 upper division units, 6 must be taken in courses offered outside your major department
Residence Requirements

For units to be considered in "residence," you must be registered in courses on the Berkeley campus as a student in the College of Letters & Science. Most students automatically fulfill the residence requirement by attending classes here for four years, or two years for transfer students. In general, there is no need to be concerned about this requirement, unless you go abroad for a semester or year or want to take courses at another institution or through UC Extension during your senior year. In these cases, you should make an appointment to meet an adviser to determine how you can meet the Senior Residence Requirement.

Note: Courses taken through UC Extension do not count toward residence.

Senior Residence Requirement

After you become a senior (with 90 semester units earned toward your BA degree), you must complete at least 24 of the remaining 30 units in residence in at least two semesters. To count as residence, a semester must consist of at least 6 passed units. Intercampus Visitor, EAP, and UC Berkeley-Washington Program (UCDC) units are excluded.

You may use a Berkeley Summer Session to satisfy one semester of the Senior Residence requirement, provided that you successfully complete 6 units of course work in the Summer Session and that you have been enrolled previously in the college.

Modified Senior Residence Requirement

Participants in the UC Education Abroad Program (EAP), Berkeley Summer Abroad, or the UC Berkeley Washington Program (UCDC) may meet a Modified Senior Residence requirement by completing 24 (excluding EAP) of their final 60 semester units in residence. At least 12 of these 24 units must be completed after you have completed 90 units.

Upper Division Residence Requirement

You must complete in residence a minimum of 18 units of upper division courses (excluding UCEAP units), 12 of which must satisfy the requirements for your major.

Plan of Study

The sample plans below show four-year plans for completing the major in Integrative Biology, taking classes only during fall and spring semesters. All lower division major requirements, except IB 77, are also offered during the summer. Peer and academic advisers are available to help customize a plan to the student's specific situation.

Please note that the sample plans below include only courses required for the major. For more detailed information regarding other requirements, including unit minimums per semester, College of Letters & Science breadth requirements, Reading and Composition (R&C), and the American Cultures (AC) requirements, please see the College Requirements tab.

  • Information about upcoming events and programs

Staff advisers are available for drop-in advising and appointments. Complex issues such as probation, academic difficulty, readmission, and major declaration are best discussed in an appointment. Please visit our advising services page for more information.

The general advising email address is ibusso@berkeley.edu. This email is checked daily, Monday through Friday, so students will receive a timely answer to their questions.

Faculty Advisers

Faculty advisers are IB professors assigned to advise students about the IB department, courses, research, and other academic issues. Students meet with a faculty adviser when they declare the IB major. Students should see a faculty adviser for the following:

  • Guidance toward achieving academic and career goals
  • Questions about the content of IB courses
  • Questions about biology fields and research
  • Recommendations on graduate training

For a list of faculty advisers and their office hours, please speak with a staff adviser or visit our website: http://ib.berkeley.edu/undergrad/advising.php. Faculty advisers are not available for office hours during instructional breaks, including summer break. Students may refer to staff advising availability during summer sessions and non-instructional periods.

Peer Advisers

Peer advisers are junior and senior IB students who volunteer their time to complement the advising services by sharing their knowledge of and experience with lower division requirements and upper division classes, experience with student groups on campus, preparation for life beyond Cal, and use of various campus resources. To see the schedule and more information about who the peer advisers are and which courses they have taken, visit their webpage: https://ib.berkeley.edu/undergrad/ibpeers.
