How to Change Your Major to GDB (Current UC Students)

Please note that you must have completed at least one full academic quarter at UC Davis and currently be in good academic standing to submit a Change of Major form on OASIS.
  1. Review College of Agricultural & Environmental Sciences (CAES) major policies and requirements.
  2. Review GDB major requirements, including the Guide to the GDB Practicum and Guide to Restricted Electives. You can find more useful resources on our Important Documents webpage.
  3. Meet with a GDB Peer Advisor to create an academic plan for GDB major requirements. Email GDB Advising at gdb-advise@ucdavis.edu with your name, SID, availability, and Change of Major advising request to schedule an appointment.
  4. Meet with CAES Advising to check GE requirements if your current major is not part of the College of Agricultural & Environmental Sciences (CAES).
  5. Submit the Academic Plan created with a GDB Advisor to GDB Advising for approval on OASIS.
    1. Select your Academic Plan.
    2. Click the green "Submit To..." button at the bottom of the screen and submit the plan to "Global Disease Biology."
  6. Declare your major using the Change of Major form on OASIS (detailed instructions here).

  • Please follow the above steps 1–6.

  • If you are: a new student (freshman or transfer) who has not yet completed a full quarter at UC Davis...

  • Please follow the above steps 1–5. You are welcome to meet with GDB Advisors for GDB academic planning and take GDB major coursework until you can submit your Change of Major form. This will be when you have completed one full quarter at UC Davis and have good academic standing established.

  • Please follow the above steps 1–4. You are welcome to meet with GDB advisors for GDB academic planning and take GDB major coursework, but you cannot submit a Change of Major form until you establish good academic standing.
