Faculty Advisors

IB students are assigned a faculty advisor during the declaration process. Developing a good student-advisor relationship benefits both parties. We also encourage you to meet and talk to other IB and Berkeley faculty, particularly those conducting research in an area that interests you.

  • Your advisor can assist with questions about coursework to fulfill requirements and career goals.
  • He/She can be a good mentor for your present and future goals.
  • Share your future goals with your Faculty Advisor, even if they might change, including what has inspired you to establish such goals.

Faculty advisors are available only during the semester. Some request that students sign up for appointments outside their offices at least 24 hours in advance; others are available for drop-in advising. See the table below for office hours, location, and preferred method of scheduling an appointment. Please note that the hours and availability are subject to change without notice.

Graduate Student Instructors (GSIs)

Establish and maintain contact with your Graduate Student Instructor (GSI). GSIs can be supportive in helping students achieve immediate and long-range goals. GSIs can also be a valuable conduit to earning a research opportunity. Add them to your network of resources and information here at Cal.
